Portable image backups

November 17, 2014 by admin | Comments Off

Just about any photographer at some point will travel to a location and photograph. That is what we do. Sometimes these locations are remote and sometimes they are just in the next town or countryside. Our captured photons are precious to us and before we can turn them into the works of art we saw when we captured the light, we need to bring them home safely. We carry extra cards, so that we do not run out of space and make sure we are able to capture that special moment. At some point we either start to run out of storage or we reach a point or have an experience that makes us realize we might want to back up and make a copies in case something happens. Something always happens, maybe not today or tomorrow but it will. Having backups is essential, especially when working for a client. Our bread and butter relies on us bringing home the goods. Many of us will travel with a laptop, then we are faced with the problem of once they are downloaded, we can format and reuse the memory card, but now we still only have one copy, or the other scenario is that we do not want to travel with a laptop and need someway of making copies to protect our precious images. Having redundant copies is essential, we do it at home, or if you aren’t you should be! Making backups is a critical function of being a digital photographer. We can carry small portable hard drives and hook them up to the laptop and make a copy of the folder. This is a good basic practice, some of us will carry two small drives and make two backups, safety first!

What about the other scenario, in which we do not want to carry a laptop or perhaps do not own one? A tablet will only hold a few images and certainly not a full days shooting or even close to multiple days, unless you are extremely frugal about capturing photons. I mean really, who only takes a dozen photographs? I am sure there are people out there but I know it would not work for me. I like to capture different angles, compositions, exposures etc. and soon the memory cards are getting full. It is not like the old days of film, where each shot was an expense, it still kind of is but not in the same sense. Shoot, chimp and check the histogram, doh not right, adjust and shoot again, that is the way in the digital age. I have found a couple of different devices that allow you to directly download a camera memory card and store them on a portable disk. They are very portable, recharge quite quickly and easily and are able to store a lot of data, good for a trip or while in the field. While they can be used standalone as the only backup on a trip, I use them as a secondary backup while out and about capturing images.  Another advantage is even if you are in the field, where it may not be possible to fire up the laptop you can still download and make a backup.

I have two portable backups, one I have had for about year or so and the other was just recently announced and acquired. The first is the Colorspace UDMA2 portable storage device and the other is the Western Digital WD My Passport Wireless. They are two different devices although they both provide portable storage. Why did I get two? Well they have different features, the Colorspace UDMA2 (UDMA2)  had a small lcd screen and and is accessed via some buttons below the screen, it has card slots for SD, Compact Flash cards. The WD Passport Wireless (Passport) has no screen, it has two buttons on the top and two leds on the front, and one SD card slot on the side. So the immediate advantage of the UDMA2 is the ability to have a menu screen and the ability to download CF and SD cards. The Passport is limited to only SD cards. I have cameras that use CF and SD but lately my main camera, the Fuji X-T1 uses the SD cards. Both units have WiFi capability, both have internal hard drives. Both units can be directly connected to computer via USB, the UDMA2 is USB2 only while the Passport supports USB3 speeds. My interest in the Passport was because of the higher speed when transferring data, although the USB specs are backwards compatible if it is truly USB3 speeds then it would make transferring data a lot faster. And when you have lots of data that can be a factor to consider.

Two types of portable backup storage for images

So how do they compare? Well the physically the UDMA2 is 5.25″x3″x1″ and the Passport is 5″x3.75″x1″ so they are physically similar in size. The Passport has built in wireless and the UDMA2 has a wireless dongle that fits into the mini USB port on the side. As mentioned the UDMA2 has SD, and CF slots, a power switch, two mini USB ports, two leds and power plug port along the sides of the unit. It has a 3.5″ tft lcs screen that has a resolution of 320×480, not real high resolution but it works for the menu system and you can see small thumbnails of the stored images. Both units can stream audio and video to wifi portable devices, this is not something I have used but it is there. The UDMA2 comes with a form fitting soft case with a belt loop and the Wifi dongle and a charger for the onboard battery. The Passport comes with just a USB3 cable, which is very short and wall wort charger, it also does not come with any printed manual, only a few pictures that really do not tell you how to do anything with the Passport.  The Passport has two buttons and a USB3 port on the top and single SD slot on the side and two small leds on the front. The Passport is available in two versions, one that is 1TB, the other is 2TB of storage. The UDMA2 is available diskless which means  the user needs to go out and get a standard 2.5″ laptop drive and install it themselves. This is what I did, I have a good fast laptop drive and installed it and followed the initialization instructions and it was up and running, a very simple process. They include instructions and the proper size screwdriver, installation is very straight forward.  The Passport is preinstalled but must be configured before the first use. Both units can be hooked up to a computer and used as a standard portable storage device, so you can also copy to and from a laptop or desktop. Both units have user upgradeable firmware.

In terms of usage they are similar and also very different. The Passport must be configured by the user before use. In order to do this, they user must connect to the device wirelessly. So either you have to use your laptop or a smartphone to access the device and then configure and setup the passwords and any configuration. The Passport may be setup to automatically check the card reader and start the download of the data. It has a very dangerous option to also delete the contents of the card after downloading, I recommend highly that you do not set this option. Also be sure to set an access password to the device, as soon as you turn on the device it will broadcast an SSID and unless you secure the device others can access it. To download a card, merely insert the card and wait. The wireless led will turn from blue to white and start flashing while it is downloading the data. It will download to a default directory and it will set the folder name to unique name that is generates. The user has no way of making a meaningful folder name for each download. When it is done downloading it will stop blinking and go back to blue, the card can be removed at that time. It will not make a second copy of that card, if you remove and reinsert the card it will look at it and decide it has already made a copy and will not download it again.  So no way to make a second copy to make sure it was downloaded. When done you can power down the drive. The Passport does not come with any kind of case.

The UDMA2 is a little more flexible in how it operates, you turn it on and it gives you a menu with items to choose from, like import a card, look at the photos on the drive, another to access the files on a file basis, make copies etc. Another menu item for the wireless. Another unique item is that it has the ability to recover images from a corrupted memory card or deleted memory card. And also has a menu to access setup and configurations.  To import images, stick a card in the appropriate slot, select the import menu item and it will check and make sure there is a card and download the card, by default it sets the folder names to card1, card2, etc. After it is done importing it allows you to look at the thumbnails of the image, it will display the basic EXIF information, like the exposure and iso and you can also have it show a histogram. Because it is using the embedded preview image and the screen is low resolution you will not be able to check focus but you can take a rough look and see the important details like exposure and the histogram. You can also browse images after they have been downloaded.

In terms of real world usage of these devices, a big concern is overall speed. I think a lot of people are too preoccupied how fast a device is, but in the case of downloading image from memory cards, I am all over anything with some semblance of speed. Here is where the big difference between these two device lies.  For testing purposes I took the same 20 raw files from my Sigma DP2Quattro camera and placed them on two cards, one was rated at 45mb/s and the other 95mb/s. Both were Sandisk SD cards, the slower card being a Sandisk Extreme, while the faster was a Sandisk Extreme Pro. I chose the Sigma files because the raw files are large, around 60mb each and this gave a total of 1.11gb of data to transfer. This turned out to be an interesting test, first there was no difference in download speed between the two cards, in other words, whether it was the 45mb/s card or the 95mb/s card, the download time was the same,  while using the built in card readers on the devices.  Also in use in the camera, with the Sigma it does not matter but with my Fuji cameras, speed matters.  If I use a fast card reader attached directly to my laptop or desktop, the card speed matters. Well that was a bit of diversion, the big difference between the two portable devices was significant. The Colorspace UDMA2 download the card in about 57 seconds, while the WD My Passport Wireless took 2 minutes and 21 seconds, yes 57 second vs 2:21 seconds. That is a big deal, especially when you are downloading a ton of data and multiple cards. On a recent trip to Colorado, my wife and I shot about 119GB of photographs, and taking 2.5x longer was an issue. While on that trip I downloaded the cards directly to the Colorspace UDMA2, then I downloaded them to my laptop, then I used the laptop USB3 direct connection to copy the daily folders over to the WD drive. For me using the SD card download on the Passport was too frustrating.

My other beef with WD My Passport Wireless is that the only way you can set it up is via the wireless interface. In other words if you connect to it via the USB3 cable all you can do is access the drive as a portable drive. You cannot access or configure the wireless setup or any of the options. My other issue with the Passport Wireless is that I had to download the manual and read it before I could set it up. By default automatic download from the SD card is disabled, and wifi security is disabled. They do provide the manual on the drive. The printed foldout  guide included was a pointless waste of paper. The included cable is very short, too short in fact, about 12″. A longer charging and interface cable is needed at least for my uses.

So in conclusion I think the Colorspace UDMA2 is the way to go for portable storage with the ability to download images from memory cards, it can deal with two types of cards, has the ability to review the thumbnails and to view exposure information and a histogram. You get to choose how much storage you want and you can easily upgrade it. Battery life on both units is reasonable but the Colorspace UDMA2 charges slower but it has a battery level indicator, it also comes with a nice soft case. The Passport charges quickly but only shows the battery level by a single led color, it will change color with less charge. The Passport is good as an attached portable drive and an SD card reader on a emergency basis. Get the Colorspace UDMA2, it is the most flexible and faster of the two. In my usage the Passport is just another portable drive to attach via usb.

 

 

Sigma DP2 Quattro – High resolution niche camera

July 21, 2014 by admin | 6 Comments

Around the end of June I got an email from Sigma, the lens and camera manufacturer, announcing their “Try Before You Buy” program for the DP2 Quattro camera. This camera was announced earlier this year and it is a predecessor to their DP Merrill line of compact cameras. These cameras are based on the Foveon sensor which records color for each pixel instead of using a Bayer matrix and interpolating the color. This leads to an increase in resolution, how you classify that is open for some debate. The DP2Q uses a new version of their innovative sensor, in that it records a full resolution luminance and blue chrominance and reduced resolution red and green layer. It still records color for each pixel.  They have a lot more information on their website.   One of the advantages is that  there are no filters in front of the sensor, and one of the disadvantages is the sensor records each color in a different layer, the deeper the layer the lower the intensity of light as it penetrates deeper, and this can lead to more apparent noise. So the sensors do not do real well in high ISO, dim light situations. The benefit of these sensors, is they can deliver a ton of resolution in a small and compact package.

 

Sigma DP2 Quattro

Sigma DP2 Quattro

The camera is not your normal looking camera, it is long and thin with an angular grip on the right hand side, which has the shutter button and main controls and also houses the battery.  The lens is a fixed lens, 30mm f2.8 and has the equivalent field of view of a 45mm lens on a full frame camera, the crop factor is 1.5x.  The grip is very angular and I found it could be uncomfortable to hold in one hand, I suppose you could get used to it but it really lends itself to being held in both hands. There is hot shoe on the top centered over the lens as well as a standard tripod screw socket on the bottom, centered approximately at the centerline of the lens and at the sensor plane. This will at least make it easier for doing panoramas. The memory card is located on the left side of the camera and has a rubber type cover that is a little awkward to remove each time you want to access the memory card. That type of cover is usually used for covering ports that don’t get used often. If you have short fingernails it can be problematic to get the cover off. That was not the best choice. The battery loads from the bottom in the grip area.  The top of the camera has a small button for turning the power on and off, a mode button for setting the the various modes, like program, aperture priority, shutter priority or manual mode. There are two rotary switches on the top, the front most one has the shutter button on it and rotating controls one of the settings depending on the mode. The rear most rotary switch controls the exposure compensation or aperture in manual mode. On the back there is a nice 3 inch lcd screen. It is not moveable or tiltable, which is really a shame.  The four buttons to the right of the lcd control various functions and includes the menu button. On the rear of the grip area is a button surrounded by a 4 way toggle. It is a directional switch as well as turning the focus mode from manual to autofocus and also for selecting the focus point. The lens also has a small, thin ring that can be used for manual focusing, it is fly by wire type focusing. The hood is a little large but usable and uses a bayonet mount to attach to the front of the lens. The lens is also threaded for 58mm filters.

Field Testing

As I mentioned earlier the grip is not very ergonomic, at least for my hands it put some pressure at points that made it uncomfortable to hold for a long time period in one hand. Using two hands was a lot better, balanced quite well.  The camera will focus quite fast if the light is decent, seems to hunt a bit in low light. There are only 9 focus points,  8 points centered around the center point. These are easily accessed, pressing down on the 4 way button and then selecting the point you want and pressing the center button to return from the selection. The drawback is that there are only 9 points. I have been spoiled with DSLR’s and my Fuji X-cameras and I am used to having a lot more focus points. When manually focusing you can press the center button on the 4 way to zoom in and check focus at the selected focus point, this is really nice. Manual focus is “fly by wire” and responsive. There are two zoom factors, but you need to press the center button to exit zoom mode. You can autofocus and then adjust the focus manually, without having to switch modes. When you select manual focus a small distance scale appears near the bottom of the lcd screen. The distances marked are very coarse and not very useful, smaller divisions would have been more helpful.

Once you press the shutter it can take a few seconds before the camera will respond again, even though there is a 7 shot buffer, it is not a fast shooting camera at all. The raw files are huge and do take some time to write out. Having a faster memory card does not help, it still takes a very long time in modern camera times. The camera is a slow and deliberate imaging device that does not lend itself to shotgunning and rapid fire.  Raw files were in the 50-65mb range, depending on details, so there is a lot of information being written out to the files. The camera can record jpg, raw and jpg+raw. The jpgs looked nice but for this camera raw is the way to go.

The 3″ lcd on the back of the camera is nice until you get out in the bright sun, then it is very hard to see anything on it, let alone try to focus and frame. This is not that unusual for cameras that rely solely on the rear lcd. Sigma does make an optical viewfinder that slides into the flash hotshoe. This will give you an idea of framing but any exposure or focus information will have to be from the lcd. Sigma did not include one of the viewfinders for the trial. I really wish they had, and I think it will be a necessary item. On the screen you can also turn on a level and tilt indicator, which takes up a fair amount of the image area and can be disabled easily, but it is useful for initial setup for a shot. Also a live histogram can be enabled. I used this a lot, however, even if the live histogram was not showing any blown highlights I was getting blown highlights. So I ended up dialing in exposure compensation of as much as a stop in bright contrasty light. I did not see anyway to enable the histogram or a blown highlight indicator when reviewing images on the lcd, I think this is really an essential feature that has been left out of the camera. The camera also has the ability to bracket shots, which is nice and it is selectable in 1/3 stop increments, up to +/- 3 stops. The down side of bracketing is that it can take awhile to write out all three shots and the camera is not very responsive.

Battery life was reasonable and I seemed to get around 250-300 shots on a battery,  however the camera does get noticeably warm. In fact it can get quite warm. I noticed the warmth on the left side where the SD card is located and also on the right side in the flat area next to the lens. It is almost if the processor inside the camera is using the case as a heat sink. On a warm SoCal day it got quite hot, hot enough that the “overheating” icon started flashing on the lcd. This is the first camera that I have that had an overheating icon, let alone having it come on. It did come on several times on a hot day, so I shut the camera off and sat in the shade and let it cool down. It would cool down in about 5 minutes or so with the camera off and then back to shooting.

Raw Conversion Software

Raw conversion is another possible issue for some users. The raw format from this camera is only supported by Sigma, the manufacturer. So you will not be able to use Adobe Lightroom or Capture One to process your raw files. You must use Sigma Photo Pro. This software is easily downloaded from the Sigma site and they have versions for PC and Mac. The software seems to have most processing features you might want to use. However it is a very slow piece of software, loading images takes some time, as well as any time you move a slider, it will take 10 seconds or so to update the image. While I realize that there is a lot of data, in today’s world that is slow and can be frustrating when you catch your self not allowing time for the update to catch up. It is not real time adjusting.  Also when you load an image it does not reset any of the previous settings that you use, so you need to go and manually resets each group of sliders by pressing on the respective reset buttons. Sigma Photo Pro, or SPP, does have a image browser so you can look at thumbnails and then click on the image to edit, and it will use two monitors if you have a dual monitor setup. One thing I found annoying is that the thumbnails, even in the “large” setting are too small to really see any details. I found that Breezebrowser allowed me to browse the thumbnails and see a larger version so I used that to browse the images to select the ones that I wanted to bring into the editor. The SPP also has a few bugs, at least the current version that I tried during this period. I found that if I set the box to save the image settings while I was saving the file out as tif or jpg, when I went back to edit another image it would crash on loading the image. This was solved by not checking that box, also it seemed that it never saved the image settings anyways, so kind of a moot point.  Another thing that was missing was any kind of curves, all adjustments were via sliders. I also found that the sharpening slider quickly resulted in artifacts so I would end up doing any sharpening in a different software. Another “feature” that is annoying, when you start up SPP, it goes out and looks at each and every drive on your system, so if you have some network drives that are “sleeping”, it wakes them up and accesses them. So you sit there staring at and empty framework while all the drives spin up, it does this even if it has never accessed the drive before. The slowness of the software was consist on all the computers I tried it on, originally I was using my laptop and thought switching to the much more powerful desktop would speed things up. Turns out that was not the case at all.

Image Quality

As with any camera the overall image quality is what really matters. After all a camera is just a tool. The size of the image from the DP2Q can be a matter of discussion, the RAW file, straight out of the camera is 5424 x 3616, which is a decent size image. You can save it, after processing in SPP, at a super high setting of  7680 x 5120 in both jpg and tif or you can save it in the default size of 5424 x 2616 or even a half size or double size image. I only save at default size and super sized, I saw no real benefit in the half size or double size images. You can also select 8bit or 16bt for the tif and you can also select the color space.  The larger size is very hard to tell from the smaller size. There seems to be a little resolution loss but I did not take enough samples to be completely sure. The larger size is certainly getting closer towards the size of medium format. Since there are no filters at all in front of the sensor elements the resolution and sharpness is quite amazing. That is if the photographer has done their job, any kind of camera shake or instability can affect image quality. So this is one of those cameras that best practices results in better images. In general I found colors to be bright and vivid straight out the processing software, white balance was pretty accurate most of the time, but in some conditions and with people the color balance seemed a little off to me. I am very used to having the white balance nailed, especially with my Fujifilm cameras and with the Canon dslr. If you look closely at the crop of the cactus image to the right, you can see a ton of detail in this image. The crop is from the upper right corner of the previous cactus image. There is no distortion that I could see with this built in lens, optical quality is excellent. The details are really amazing, the crop is at 100% and no additional sharpening was used. Notice the fine details in the fuzz between the spines and the rings on the spines. The bokeh at wide open apertures was quite pleasing and having the f2.8 was nice.

 Final Thoughts

Well it was too bad that I had to ship the camera back to Sigma, I had it in hand for less than a week. I wish I had some more time with the camera to really put it through its paces. This was the first Sigma camera that I had used, I have used many of their lenses. That being said I had read about and researched their DP Merrill series of cameras, the one that this DP2Q is replacing, and I often lusted after one. I did understand the shortcomings of those cameras but the images were compelling with lots of detail. This new generation is along those same lines. There are good things, and some not so good things about this camera.

The camera is capable of taking amazing images with fantastic detail, if the photograper is careful and uses best practices. That means careful focusing, stable platform, watching shutter and aperture, taking the time to get things right. It is not a point and shoot. It really needs to be shot at low ISO ranges, the camera is capable of 6400 but I think a more realistic limit for color is about 800, and you can do a lot with black and white images up to ISO 1600, beyond that it is not that great. Image quality degrades, lots of noise and blotching. So keep it low ISO.  I put a Arca swiss type release plate on the camera and used a tripod as much as I possibly could, this slowed things down and made it deliberate, which is what this camera needs. It is slow, in a relative fashion compared to other cameras, but not really that slow compared to cameras a few year ago, and those had much lower resolutions. Watching exposure is a must and sometimes bracketing is needed to assure that you captured the image. The controls are well laid out and easy to change and are well thought out, just the grip leaves a lot to be desired. I did try the flash that was sent with the camera, it worked ok and seemed to do an adequate job, not something I would use much with a camera like this, but if you need a quick shot, it is worth it. The software is slow, no matter what machine you run it on, it takes some time to get used to it. The best thing to do with the software is adjust exposure, white balance, lower sharpening and output a 16 bit tif and edit in some other software with more features.

What it really needed was some sort of electronic or mechanical shutter release, there might be one, but unless it uses the USB port I did not see anyplace to attach it. That would be nice to have, especially when using a tripod. Another nice thing to have would be an optional Electronic View Finder, but I don’t see that one happening. A tilting lcd screen is also something I really wish they had on this camera, the might mitigate some of the bright light usage issues and also make it easier for tripod use. I am not sure how well their optical finder works, as it was not included.

So in conclusion, it is capable of amazing images if used with care and some tolerance of quirks. In other words a nice camera that will have an appeal for those who can appreciate a niche camera. If you are looking for a snappy point and shoot to chase the cat around the house, this is not the camera for you. If you are looking for a camera that will challenge you to get the best images you can get, then you have room in your bag of tools for this camera.

I still have a backlog of images to process but here are few more samples. Click on any of the images to see a larger version.  Feel free to contact me with any questions, and if you are with Sigma and want a tester…….. be happy to help. Thanks for reading.

UPDATE: 30 July 2014

I just wanted to clarify a few things. In my look at the DP2 Quattro I was wrong about the blinking highlights, those can be viewed during the review process, I read about it in the manual, when I get the camera I will be sure to enable it. The other thing is that Sigma is making a release for this camera, it plugs into the USB port and is relatively cheap to purchase, it is a simple button with a hold function

Sigma has also announced that within the next two weeks there will be a camera firmware update and an update to SPP, hopefully that will clear up a few of the bugs.

Update on the Rokinon 12mm f2 NCS CS lens

June 9, 2014 by admin | Comments Off

A brief update on the Rokinon 12mm lens that I previously reviewed. I did get another copy of the lens and color cast that I saw in the previous lens was gone. So that is great news. I have shot with the lens some more including getting out and shooting under the stars. One of the main reasons I was interested in this lens was it might make a good lens for nightscapes. I have to say that it really does make for a good lens for night shots. The lens is still a bit soft at f2, but that is to be expected with a lens that is this wide. It is not to say that it is unusable, but it does perform better stopped down. If there is nothing close to the lens and most items are at infinity focus then it is hard to see the softness.  For most instances this not a problem and it is a wonderfully fast lens. I found that stopping down to f2.4 or f2.8 resulted in a general improvement, and by f4 is pretty good all over. That being said for quick nightscapes the faster aspects can be beneficial, and it will show less trailing. Even though this is a wide lens, with the crop factor it does give the field of view of an 18mm lens so that means that stars will start to show trailing before 30seconds, depending on where you point the camera.

This shot was from a quick trip out to Joshua Tree National Park, taken with a Fuji X-T1 and the Rokinon 12mm at f2.0 and ISO 3200, single exposure of 30 seconds.

The lens is a good deal considering the price and the performance. The downsides are the full manual focus and aperture and the lack of details being recorded in the EXIF of the camera. The Fuji does allow the setting the focal length so that is recorded, however the aperture used is not recorded. The lens hood also leaves something to be desired. It is really loose fitting and will sort of snap into place but there is a lot of play and I have found that it has come off sometimes in the camera bag, poor design, in my opinion. It is a functional hood for the wide angle lens but it could be better. The positives pretty outweigh the negatives. There is little chromatic aberration and little coma in the corners. I do expect some in a lens this wide but it is very negligible. Color and contrast are quite good. It has well corrected optics, much better than one would assume with a lens of this price point. It is also compact and relatively small for a wide angle lens. Focus ring and aperture ring are smooth and have a good feel to them. The aperture ring is detented at half f-stops from f2-f22. The lens feels solid and well constructed and is not weather resistant. The front is threaded for 67mm filters, which is nice.

I would recommend this lens, especially for the price point.  I would give the Fuji 14mm f2.8 lens the edge, it has the full autofocus, as well as manual focus and the ability to have auto aperture, but the Fuji is substantially more money. The Rokinon is a bargain and for me a nice lens to have in the bag and one that will get used, for nightscapes and landscapes. I will still keep my Fuji 14mm. The Fuji is a bit better corrected optically but the Rokinon does pretty well. The extra 2mm of the Rokinon does make a difference. I was also interested in the Rokinon 10mm but it is twice the weight of the 12mm and is not as appealing. The 12mm was designed for mirrorless cameras and therefore the size and weight are scaled accordingly, while the Rokinon 10mm appears to be a verison of their DSLR lens with a Fuji X-mount on the end, not as appealing. I am happy enough with this Rokinon that I do not feel the need to compare it to the Zeiss 12mm lens for Fuji.  For ultra wide I will stick with the Fuji 10-24mm f4.

Rokinon 12mm f2.0 for X-Mount – a first look

Rokinon 12mm mounted on the X-T1

The Samyang/Rokinon 12mm f2.0 for x-mount was recently announced and has arrived in the stores. Samyang is the original manufacturer and the lens is also rebranded and sold under several names, including Rokinon.  I ordered one to take a look, nice and compact and it was certainly priced right. It is manual focus, manual aperture with no EXIF data being sent to to the camera, which is something that really irritates me, but oh well. At least Fuji anticipated that people might use other brands of lenses that might not provide that information so you can at least set the focal length using the camera menu. This allows you to identify the lens when you are using it in the field, but you do not get any aperture information.

I received my copy of the lens, packaged well for shipment in a plastic shell with a small manual and small cloth bag to hold the lens if needed in the camera bag. The lens shade is detachable and made from plastic. The locking mechanism  for the hood seems a bit weak and may wear after some on and off use, maybe not but I do not have a lot confidence in it. The aperture ring is smooth and has half stop detents from f2 to f22. The end of the lens barrel is threaded for 67mm filters. The focusing ring was smooth and gives a nice feel when focusing. The lens itself seems to be well built and rugged, it is not weather sealed. When inserted into the camera there is some play, it did not lock in place firmly.  I was able to twist and shift it a small amount between the stop in the lens mount, since there are no electrical contacts this should not really be a problem, although I wished it would lock in place better, this might be just manufacturing tolerances. The lens is light enough that it balances well with the camera.

Static testing

Distortion test

Distortion test

So off to shoot a few sample images. First off I wanted to see what kind of distortion I might get from a lens this wide. I figured there would be some distortion, it is hard to make a completely rectilinear lens and this was not an expensive lens by any means. The Samyang 14mm lens for dslrs had a really strong moustache type distortion which could be problematic.  So for my first target I set up a grid made from a filter from an air conditioner, it was   setup to be level and the camera was mounted on a tripod and square and level to the grid. As you can see from the image there is very little distortion. A small amount of barrel distortion that would be easily fixed in post processing, when and if you really needed to fix it, it most shots except for architecture you would probably not notice it.

One troubling thing, if you look on the image to the left is the yellowish color in the middle from the top to the bottom of the frame. This is not the color of the wall, and I did see this on the screen while taking the images, it is present in the images. The wall that this is on is a uniform blue color. It looks like it might be some issue with the coating or the type of coating with this lens, I don’t know if this is just my sample. So I brought out my other test chart. By the way these test charts are just something I threw together for me to see how lenses perform, other than careful alignment and doing the best I can to level and keep things straight, there is some room for some error. Not scientific at all so remember that.  Anyways, the next chart is made from some lens test charts by Norman Koren, downloaded and printed on white paper with my epson printer. They are mounted to a foam core board that is slightly yellowish and there are some spray glue remnants, remember this is not scientific, just my take on testing.

Up the chart went and everything was aligned. Test images were taken at all apertures. My purpose for this test was to see corner

Lens sharpness and vignette testing

Lens sharpness and vignette testing

sharpness and vignetting and overall lens sharpness. This image to the right was shot at f5.6 and also shows the same yellowish patches from the lens. Again this is disturbing. However, the lens is pretty sharp overall. Especially in the center, which is pretty typical of ultra wide angle lenses. At f2, which is wide open for this lens, it is somewhat soft, however the sharpness is acceptable at f2.8, both center and edge. The corners do not really get sharp until around f4 without sharpening applied and pretty good at f5.6. Below in the gallery are some corner crops from the upper left corner. Also there is pretty significant vignetting at f2 and gets reasonable at f4 and beyond. Click on the images to see larger versions and for the corner crops they are 100%.

Real world imaging

As I mentioned the color cast in the middle might not be noticeable in real world images. I did go out and shoot a few images in the real world.  These are shot at f11. The first was hand held and the second was on a tripod. Click on the images to see larger versions.

Here is a comparison shot with the Rokinon 12mm at f11 and the Fuji 10-24mm at 10mm and f11. The tripod was kept in the same location, just the lens was changed in between shots. You can see that an extra 2mm can make a difference in the field of view.

Conclusions

I was really hoping that this was going to be a great lens, the price was great, and Samyang has made some great lenses in the past. This lens is a little smaller than the Fuji 14mm f2.8 and has the same focal length as the Zeiss Touit 12mm f2.8 but at half the price. This price differential is what was really appealing for the Samyang/Rokinon lens. The build quality is there, the minimal distortion and the pretty good control of vignetting, and the corner sharpness even at wider apertures make this a really wonderful lens. The only thing that could be a problem is this discoloration I saw in my static testing. I am hoping this was just an aberration of my testing or my copy of the lens. I will give another lens a try and see if I can get a better copy, but before I send it back I will redo some of the testing on some different subject matter. The reality is that it is probably not noticeable, but I know some light colored building I will have to give it a try and see before I return it.

Is this a replacement for the Fuji lenses? No I don’t think so, it might be a nice addition or if you are on a budget it might be a good lens to get. It is really hard to beat the Fuji 14mm f2.8 or the Fuji 10-24mm f4, they are very high quality lenses.

Pimping the X…..

April 10, 2014 by admin | Comments Off

Have you ever noticed that nothing is perfect out of the box?  They can be close to perfect but soon you notice a few wrinkles. A little more time and then comes the need for some enhancements. I am not talking about that “eX”, there is little you can do about that, but I am, of course talking about the X-series cameras from Fujifilm. These compact wonderful little cameras just beg for a little enhancement. Some of the enhancements are just cosmetic and maybe you have gone through that with your “X”. There are some that are really needed to enhance the experience and the usability. Let’s take a look.

Grips, tripod plates, thumb rests and other handling enhancements.plates-web

Lets face it, these are small cameras and there can be some issues with handling. They were not as problematic as I envisioned them. When using the X-Pro1, X-E1, or X-E2 I think a Thumbs Up thumb rest is a mandatory item. It gives me a nice comfortable but firm grip with my thumb, the disadvantage is it uses the hot shoe so it has to be removed when using the flash or a flash trigger.  That is unless you use the sync port on the X-Pro1 or X-T1. It does prevent me from hitting buttons on the back of the camera as easily by mistake. Yes the original Thumbs Up is expensive but it is well made, fits perfectly so you pay a bit more for a quality product rather than cheap knock off. It always surprises me when people gripe about the cost when they spend $500 on a bag to carry the camera, but I guess it is all relative. The X-t1 has a different design for the body and does not lend itself to the use of a thumb grip, like the rangefinder style cameras.

Soft release is another essential item for the X-series at least up to the X-T1. At first I thought the soft releases were just joke and how could they make the shutter button better? Well once again, use and testing revealed otherwise. The cameras up to the X-T1 have a screw in shutter release capability, just like the older film cameras, the soft release screws into the shutter button and really does change the feel of the button and how it operates. I wish the X-T1 could use one, although I see that at least one manufacturer has a stick on version for the X-T1 now. The button on the X-T1 does feel pretty good, or I am just getting used to it, since there are not many options.

When doing landscapes, nightscapes, and long exposure photography a good tripod mount is needed. Fuji in their infinite wisdom (sarcasm alert) decided to put the tripod mount screw offset from the lens center and close to the battery door. I don’t know what they were thinking, any kind of quick release plate and you are blocking the battery door. The grip for the X-Pro1 was nice in that it attached to the bottom, gave a nice larger grip to hold and moved the tripod screw to the centerline of the lens but they still blocked the battery door!!! Well Really Right Stuff to the rescue. I use Arca-Swiss compatible ball heads so the RRS L-plate incorporated the ability to use the Arca-Swiss style ball head, and still allowed access to the battery door without having to remove the plate. The RRS plate also has an optional grip but I found it unnecessary on the X-Pro1. The RRS has a better build quality and is well worth the extra few dollars than the cheap knock-offs. They are currently developing an L-plate for the X-T1. The optional grip attachment just did not feel right to me, it was machined aluminum and I like the leatherette feel like on the body and that grip extension just changed the feel too much and added some weight to the camera.

For the X-T1, Fuji did listen to customers and critics and came out with two different grips. One is a battery grip that holds an extra battery as well as additional controls for use while in the portrait orientation. I originally thought I would find this an essential item, like I did for my dslrs, but for this camera I do not think it is needed. You do get the extra battery and so it would take twice as many images on a charge, but when it comes time to change the batteries, you have to take the grip off to change the battery in the camera. That could be tiresome but I guess you would get used to it. The attraction to me for these cameras is the compact size and I am sure that the battery grip is useful, I think it changes the camera to one that is no longer as compact. This commentary on the battery grip is coming from not actually handling one but after handling the X-T1 I just feel it does not need the added weight. I reserve the right to change my mind!

They also made another grip, that adds a thin bottom plate that is also Arca-Swiss compatible as a quick release plate for ball heads, and it added some extra grip to the front of the camera. And low and behold, you can access the battery and change it without removing the plate! Also it moves the tripod screw to the optical centerline. The MHG-XT as it is known looks to be a good addition, I am still getting used to mine, not sure I am happy with the feel of the new grip and how it changes how I hold the camera. It is a little bit different grip, but enough to make it a little uncomfortable. It also lacks a L extension for portrait orientation while using a ball head. It is well made but it may not last in my inventory. I think an RRS L-plate will be of more use to me.  Some of you are wondering why I would want an L-plate when the Fuji grip already has the quick release style plate, well when you move a ball head 90° you limit some of the movement, so it is not as easy to position as it is to just reinsert the camera in the portrait orientation from landscape orientation. When using a L-plate in portrait orientation you have a full range of motion available, just like when the camera is rotated to landscape orientation. The MHG-XT is well made and fits the camera very well, a nice addition but still waffling on this one, it just may take some time to get used to it.

Cases_MG_3010-web

Cases are a mostly cosmetic enhancement, more bling than functionality but there is some utility. I am not a fan of full leather cases in general, but the rangefinder style body in a leather half case just looked cool. I admit it, it was a blast from the retro past with a tinge of hipster that I am loathe to admit. I started with film cameras and manual focus but I never had a rangefinder or used one. I was intrigued with them and I have some older cameras that I inherited that have leather cases. So off to Ebay and a search for some leather cases and I got a tan leather half case for the X-Pro1. It looked nice, it fit nice, it did offer some protection, enough to rationalize its use and a bonus is that added some thickness to the grip and that with the Thumbs Up made for an easy to hold and use setup. The leather case also added a tripod screw, so good to go for tripod use when needed.  There was a bump in the road, the battery door was blocked, you had to remove the case to access the battery and the memory card…. arrrrrrr. So with a little wielding of a sharp knife, some patience and a little blood, there was an access port in the bottom, the case could stay on, at least while being used hand held. it looked good and when doing landscape work I could either place a small release plate on the bottom or for full blown dedicated photon harvesting, change out the case for the L-Plate. Versatility and style……_MG_3011-web

The case for the X-Pro1 worked out so well that I decided after getting the X-T1 to add a leather half case. Gariz was out early with a case designed for the X-T1. Again this was off of ebay directly from Gariz in Korea. Several colors were available, the medium brown was really tempting, however I opted for the black. Fuji also had a leather half case available in black but I heard initial reports that they blocked the SD card door! You had to remove the case to get at the memory card….noooooooo Fuji how could you  have designed this into the case? The Gariz did not block the access to the door or the battery door on the bottom. Gariz also installed a metal bottom plate and added a tripod screw along the centerline of the lens. The on and off is easy with ringed screw to allow tool less installation and removal. The ring on the attachment screw can also double as a ring for sling type strap. After a short time, my airmail package arrived and inside was a nicely made black leather case with a chrome plated bottom plate. The workmanship is excellent and the fit is excellent. What could go wrong? Well actually a minor detail, the half case fit so snugly that it prevented the lcd from tilting. The lcd was hitting the nice bottom padding, you could loosen the attachment screw but that was not a good solution. On the Fuji X-forum another user posted about the same problem and had a brilliant solution, a small paper shim. The shim worked wonderfully, a couple of small pieces of heavy weight paper and that allowed enough space for the lcd to tilt in and out easily. If you are looking for a leather case, I can highly recommend the Gariz case, well made, fits perfectly, well designed and engineered. May need a couple of strips of paper as shim, but that is just a minor issue. Well worth it.

Straps and bags and protection

Well this is a topic that can be a highly personal one, me I am not too fussy with straps. I am mostly concerned with comfort and functionality. How it looks is secondary, yes I know that sounds contradictory when I was nattering about the leather case. It is what it is….. So I use a webbing and padded nylon type strap. Something that looks decent and comfortable, no way am I going to spend $250 on a thin distressed leather strap. I do have limits to my insanity. I have always used neck straps with the camera hanging down to my chest. The Fuji now has me considering to try a wrist strap, something I have always thought I would not like. I am keeping an open mind and will give one a try and see how it works for me in real life.

Bags are a topic for another post, my quest for the “right” bag is still on going. I am not sure that it will ever be finished. Doing photography for over 30 years has taught me there is no perfect bag, yet. I keep hoping. I have gone from shoulder bags, to backbacks with impossible loads. Then to the smallest bag I could fit the mirrorless camera in and now heading towards the messenger type bag. No bag seems to have exactly what I want when I want it. Most of my bags are nylon, I just cannot justify those fine leather cases that are too tiny for use and cost $300-$700. Nope can’t do it. Cameras and optics I will spend the money on, but a bag just because it looks cool and costs $500, no way. A lot of those trendy, hipster style bags of canvas and leather are just not functional enough for the price. There are some that look cool, and I am sure they worth it, but I just cannot justify them. I am sure that some will think I am just dismissing them but I just don’t see the need to spend that much on a bag when there are others that will do the job just as well.

LCD screens on the back of the camera can be a problem depending on how you handle the camera. I always use a protector on the LCD screen, this prevents scratches and accidental marks on the back that may interfere with reviewing images.  It can also affect your view when you use the back of the camera to compose a shot. I do try to handle my cameras carefully but accidents do happen and the more you use a camera the more chances are that something may happen to it. One of my reasons to get the Fuji x-cameras was to have a light weight, easy to carry camera, so I carry it with me almost every day. Wear and tear does happen. LCD screen protectors are cheap insurance, easily replaced and worth every penny.

A soft cloth or wrap can help protect your camera if your bag does not offer enough protection. My Thumbs Up  is starting to show some brass from rubbing through the finishing on the end from caused by the small bag it is usually carried in. When I first got the X-Pro1 I had the three individual primes, so that is what I carried and had a bag just big enough to house them all, so there is a little friction in the bag. Now with more gear I need a bigger bag but a lot less bag than for the dslr.  Also fingers and constant use cause wear and tear and the camera is starting to develop that used patina.

When it was time for my wife to get a new camera, we got her a nice shiny new X-E1 and also added the lcd protector, L-plate, Thumbs Up and soft release. She also thought all of that made for a nice improvement in handling.

So in conclusion there is not a lot of enhancements needed for the X-series cameras,  they are fun, functional and easy to use cameras. Add a Thumbs UP, lcd screen protector and maybe a grip or case and something to carry it all in, is all that is needed for a good time. It will make handling better and I think improve the overall experience.  For the X-T1 there were less gadgets to get Fuji really does listen to user feedback and does change for the better, just look at the firmware updates. A great system to buy into in my opinion. Another add benefit for me is I spend a lot less time looking for gadgets and more time shooting and using the camera, what a great concept. The X-series is made to be used.

March 18, 2014 by admin | 3 Comments

Well to add to the confusion and general information here is Yet Another Rolling Review of the new Fujifilm X-T1 mirrorless interchangeable lens camera. I decided to write up a few of my initial observations and why I wanted to get this camera. I have been using the X-Pro 1 since shortly after it came out in 2012. A great small lightweight, easy to carry, all day type of camera. I got it to supplement my dslr. Something handy to carry, you know the camera you have with you is the one you are going to use most often. It was never a replacement for my dslr, but it is damn close.

The X-Pro1 has a great feel to it, I enjoyed the freedom from carrying a heavy camera. The Fuji lenses are some of the best around, the price reasonable. So what was not to like? Since it was a retro styled camera, it was truly retro, there was no ability to use an electronic release, something I often use in landscapes and long exposure photography, it had a threaded shutter button like my old film cameras. It used a mechanical release. While that would work, I like using a soft release so that meant unscrewing one and using the other and then possibly losing the soft release later.  Fuji later released the X-E1 and X-E2 cameras and they appealed to me but did not fit as well in my hand and they had my missing release capability. I was ready to pull the trigger on the new X-E2…… and then they announced the X-T1. Oh this was nirvana, true bliss and a bad case of G.A.S. developed. I wanted it. I read everything I could, followed the rumors and waited, not patiently, to pre-order. That day finally happened at the end of January of this year. About a month later the wait was over… it arrived!

So what was gained with this new addition.

1. The EVF, larger, better, faster and very usable. The X-Pro1 had the nice switchable hybrid viewfinder, I could switch from optical to electronic with the flip of a lever. I had pretty much used the optical initially but after time I wanted a better and more accurate framing in most circumstances, so I was mostly using the EVF on the X-Pro1. Also with longer focal length lenses the optical viewfinder just did not cut it. The X-T1 has a much better EVF. A very big difference.

2. Focusing, the X-T1 uses both phase detect and contrast detect methods. The X-Pro1 used only contrast as it lacked the phase detect pixels. This faster autofocus is nice in some circumstances but it was not a “have to have”. I think people on the forums rant and rave about autofocus speed way too much. People used fully manual focus lenses for a long time and were able to capture action, wildlife, you name it. I think this is more of an issue because of modern society puts more emphasis that everything needs to be “now”. Instant gratification, instant delivery. While nice, not critical for me. So just as accurate as before but faster.

3. Ability to use an electronic release, very nice for me. Intervalometer here I come… Also a really nice feature is that there is a built in native intervalometer in the camera! Bonus! Best of both worlds. Timelapse waiting to happen.

4. Faster recording of data to the card and faster frame rate for rapid exposures. Not a mandatory feature but a plus for those times it is needed. Also raw files are 14bit while with the X-Pro1 are 12 bit, that means there might be a difference at extremes for capturing more dynamic range. Might not see it in day to day use.

5. Ergonomics. This is more personal, but I like the layout of the buttons, much better for easy functionality. Dials that are easy to set and see. The grip is very nice and comfortable. I was worried that it would be too small as it is slightly smaller than the X-Pro1, nothing to worry about. I thought I would have to have the battery grip for it to be comfortable, but that is not the case at all. Having six function keys that are user configurable is wonderful. The screen tilts, this was not high on my list of features but it is useful. There has been some flak on the net about the directional buttons being too flush, yes they are different and quite flush. Yes they did feel odd at first, but after some use, it is easy to find them and the muscle memory is slowly adapting. So a definite plus in usability.

Like any product, it is not perfect. Nothing is, we just need to adapt, makes life interesting. None of these issues are deal breakers for me.

A. Exposure bracketing. This has been an issue since the X-pro1. The camera only allows +/- 1 EV automatic bracketing. This is just not enough, in my opinion. I would like to see a minimum of +/-2 stops but better yet would be +/- 3 stops or programmable range. And the ability to set the step size and the number of images per bracket.

B. I would like to see the histogram remain live and usable when the shutter is half pressed. Metering should not stop.

C. Tethering capability. I would love to see the ability to tether and have complete control over the camera from a computer. The wifi app for the X-T1 is very limited. Full tethering would be a great feature. It would also allow the user to control bracketing, exposure, and do bulb ramping etc.

I am sure there are other things that I will find over time, but then nothing is perfect. The camera is just a tool, and as a tool this is a very usable camera. Form, fit and function. Will it make me a better photographer? No, but any camera that is a pleasure to use will get used more often, and as we all know, practice makes perfect.

“Slow” an ebook review

November 14, 2012 by admin | Comments Off

Craft and Vision has released their latest ebook, called “Slow – the Magic of Long Exposure Photography” by Andrew S. Gibson.  As you might guess this ebook is about long exposure photography. Mr. Gibson has authored several other ebooks that are available on the Craft and Vision web site. This book covers a lot of different techniques, shows examples and goes over the necessary gear and recommended camera settings. The sample images are quite well done and will serve to provide some creative inspiration for the reader to go out and try something new. Techniques covered include panning while exposing, and also what is known as In Camera Movement or ICM. ICM can look a lot like camera shake and while you experiment with this technique it can get frustrating but it is possible to create some very interesting images, it can be very artsy. Gibson also suggests checking out the ICM group on flickr, I also recommend that, if you scroll through some of the pages, there are some very, very creative images. There were some of some aspens in fall color that had a very painterly type quality, beautiful and impressionistic. None of these techniques are new, I first read about them in a book from Freeman Patterson called  “Photography and the Art of Seeing” but it is nice to have a refresher.

Another chapter is devoted to using flash while doing your exposures, the flash is used to freeze the main subject, a person perhaps, while allowing the area that is not illuminated to be blurry or show motion. One of the examples is of a  lady on a revolving carousel, and the background shows the motion in the background and the subject  is frozen in time because she is illuminated by the flash. He explains the difference between first and second curtain sync.

Andrew also covers the more traditional long exposure images, from several seconds to minutes or even longer and generally using a tripod for support. He goes on to explain the advantages of neutral density filters and polarizers. In addition to the information and examples he also includes interviews with two other photographers who use long exposure photography but with very different styles, with examples of their work, so there is plenty of inspiration available.

This ebook is quite reasonable and is normally priced for $5, however, you can get it for $4 if you use the code “Slow4” when checking out from Craft And Vision. If you would like to get more than 1 ebook use the code “Slow20” for a 20% discount on 5 or more, both of these codes expire on November 18, 2012.

I recommend the ebook if you are interested in long exposure photography or just want to learn more or be inspired to do something different, the techniques are pretty standard but it is a source of inspiration and good refresher.

A look at the Samyang 8mm f2.8 fisheye lens on the X-Pro 1

October 31, 2012 by admin | 8 Comments

Samyang announced that they were going to produce some lenses for the Fuji X-Mount and that was good news to me, they have made quality lenses for DSLRS so I was interested to take a look at what they had to offer for the X-Pro 1. The first in a line of X-Mount lenses,the 8mm f2.8 fisheye is a smaller version of the lens used on DSLRS.  The original DSLR lens is designed for an APS sized sensor, but I found it also worked quite well on a full frame camera if you removed the lens shade.  I searched on the internet and did not see a lot of examples with the X-Pro 1, so I decided to rent one to give it a test drive. I have been using Lensrentals.com as my main provider for rental gear, they have been great to deal with and I recommend them highly. When I saw they had the Samyang 8mm fisheye in stock, I placed my order. I usually like to rent something before buying, especially if I am not sure I am going to really want it, also to test performance and quality. Sometimes  I am just curious. Below are some images of the lens on my X-Pro 1.

Fuji X-Pro 1 and 8mm f2.8 fisheye   Fuji X-Pro 1 and 8mm f2.8 fisheye

Lensrentals.com had in stock one of the rebranded lenses. Samyang sells under their name, as well as being rebranded by Rokinon and other lens brands. The quality is the same. Samyang is a Korean based manufacturer that has some excellent optical quality lenses available for affordable prices. I have their 14mm f2.8 and 8mm f3.5 lens for Canon EOS and have been really pleased with the build  and optical quality, the images have been really great from these two lenses. My only real issue with them is they lack the chip to transfer the information about the lens to the camera, so the camera does not know what lens you have on, or what the focal length, or what aperture is currently set. They do offer that for some Nikon lenses, I sure wish they would offer it for Canon!  The Fuji X-Pro 1 is no exception, there is no communication with the camera. Luckily the X-Pro 1 allows you to set a focal length from the menu but you still do not get the aperture information. Bummer!X-Mount and EOS 8mm fisheyes compared

The Rokinon 8mm f2.8 for X-Mount arrived safely from Lensrentals.com and came with a small case to carry the lens. At first glance this lens is really tiny when compared to the EOS version. Pictured to the right is the EOS and X-mount versions compared side by side. The EOS version is mounted on the Kipon X-Mount to EOS adapter  and the lens shade has been removed. I did this to allow it to be used on a full frame camera. Samyang now sells it with a removable shade. The build quality of the smaller cousin is up to the normal standard for Samyang. Well made and not cheap feeling.  Th focus ring is smooth and the aperture ring has nice positive stops. The aperture ring is only in half stops and not thirds. The lens is nice and compact and about the same size as the Fuji 18mm f2 when compared side by side.

18mm compared to 8mm

The electronic viewfinder is the best method of focusing and framing while using the X-Pro 1. The field of view is so extreme that you really do need to see what the sensor sees.  This lens is considered a full frame fisheye, and this is full frame not in the sense of sensor size but the fact that the image is the equivalent of taking the largest rectangular image out of a spherical image projection. This gives an approximate 180 degrees field of view from corner to corner on a diagonal across the long side of the sensor and it does comes pretty close, but hard to actually measure.  This means that if you are looking to do equirectangular panoramas then you will also need to shoot a nadir image and a zenith shot. Shown below is a 360×150 degree panorama flattened, the zenith and nadir were cropped because I did not take those images. So the edge to edge coverage across the long side is 150 degrees. Six exposures, taken with a lot of overlap and assembled in PTGUI. Of the sample images shown this was the only in which a tripod was used, along with a RRS panorama head. With careful calibration you could take the image as 5 exposures and include one up and one down for zenith and nadir coverage.

The fisheye distortion can be corrected in software, there are currently no lens profles available for this camera and lens combination but they might be available at some point. PTLENS, Adobe Camera RAW,  and Lightroom will allow you to correct the distortion manually. Photoshop CS6 can also correct for fisheye distortion, that is a new feature with CS6. However the distortion can be interesting and can be used in an artful manner, so it is up to the photographer to decide what post processing is necessary.

The image quality is quite good and it can focus quite close with a huge depth of field. So manually focusing is quite easy and easy enough to just set an approximate distance and be quite sure that most all will be in focus. Like any uber-wide angle lens, shooting it wide open at f2.8 and also because of the fish eye distortion, the corners of the image can be a little soft but it is totally usable and stop it down a bit and you won’t notice. The lens coatings seems to handle flare pretty well, although with something this wide it is hard not to get some flare. Color and contrast are good.

The extreme wide angle can also create some other “issues”. I normally hold the camera with my right hand over the shutter and gripping the camera while my left hand cradles the lens so that I have fast access to the focus and aperture rings. While using this lens you have to be careful as I found I was often getting my knuckles and part of my hand in the shot! Also while holding  the camera, especially in the portrait orientation, tilting the camera down slightly often caused me to get my elbow or my feet in the image. So you really need to scout around the viewfinder and look at the whole frame before pressing the shutter button.

So is it worth buying?  I would say yes. It is certainly not a “must have” lens but it is an interesting lens with a novel effect which can be used quite creatively. It can also  be used to create stunning virtual tours using an appropriate panorama head on a tripod. Price is reasonable and the build quality is good, so if you are in the market for a specialty lens like this, I would definitely get one.

Below are some sample images. The interior shots of the church are taken with the camera resting on the pews at very high iso with bracketing. When the light is so low and shutter speed gets down to 1/30 of a second the camera will bracket using the ISO, when in autoISO mode, so that can be useful. The highest ISO used was 6400. The other building shown is the Pasadena City Hall, one of my favorite buildings to photograph. I did not do any distortion correction in the sample below.

Portraits of Earth – a new ebook

September 5, 2012 by admin | 2 Comments

Portraits of Earth is the new ebook from David DuChemin. David is a photographer who has been known for taking people portraits and showing the human side of events, so what is he doing writing a landscape photography book? Well, like David mentions in his ebook, landscapes are really just portraits of the Earth. They can inspire as well as inform the viewer, emotions can come into play and just the sheer beauty of nature is something to share. This ebook is not so much about gear, but about looking for the possibilities and crafting your shot with more care to complete your vision. He also gives some tips for gear, and how to use it to capture the light that you see when exploring new vistas. He talks about filters and how they can enhance an image and the best ways to use them. He also talks about some general gear, like tripods and other useful items.  He also goes into details about how to handle specific types of scenery, like fog and snow. Also there are some nice tips for some processing techniques and can give you some ideas to try in your own images.  The book is filled with pictures from his travels around the world, visiting places most of use are not going to see, I know I wish I could go to some of these places. So does that mean you have to travel to exotic locations? No it does not, but he does show you through examples of how to apply leading lines and to use light to tell your story and capture your vision as well as composition topics and some discussions on why and how he made the images as well as the exposure information.

So why should you consider this ebook? Well for me I like the way David writes, his writing style is easy to read and understand and you feel that you are having a conversation with him, he explains his motivations and tries to not make it too technical. Photography is a an artform that requires some technical knowledge but it also requires the artist to “see”, so there are fuzzy concepts to go with the  geek. You can purchase this ebook for a very low price of $5, however if you click on the link and use the code EARTH4 before Sept. 9, 2012 you can get it for $4, Click here for Portraits of Earth While you are on the Craft And Vision site you might want to check out their other ebooks. I have personally found the following titles to be very useful, The Power of Black and White, Light and Land, Exposure for Outdoor Photography, and Close to Home, all of the ebooks on the site are well written and informative, and if you want to get several ebooks use the code EARTH20 for a 20% discount on 5+ ebooks, this code also expires Sept. 9, 2012.  So get some good, cheap, informative ebooks and inspire yourself to get out use what you learn. I know I have.

 

Dodging and Burning – An essential skill and a new ebook to help learn the basics…..

July 17, 2012 by admin | Comments Off

Many of us “old timers” got our start with film cameras and darkroom work with chemicals and all kind of trial and error methods to bring out the details in our photos like dodging and burning. I remember having all kinds of funny shaped cardboard pieces on little pieces of wire and cardboard with cut outs and sometimes just using your hand to help bring out details in a print. In newer terminology to bring the full dynamic range to view on a nice print. Today, of course, we can use computers, so instead of throwing away trial prints we can edit and experiment. Especially with tools like Lightroom, the changes are all parametric and we can always go back and re-edit. You can still do that with Photoshop but it takes a little more effort. Now we use pen tablets and a mouse to apply and change the areas, to make the highlights and shadows as we remember the scene or how we want it to look. All of us go through various learning curves and it is always useful to learn new techniques, so that brings us to the subject of this post. Here is a new ebook, available from the fine people at Craft and Vision. This new ebook is quite a package, it includes an ebook on Dodging and Burning, including lots of examples, but it also includes some Actions for Photoshop and a custom Panel for interacting with the Actions. The sample images discussed in the book are included so that you can follow along exactly with each step. These are set up for Lightroom 4 or Photoshop CS6, while they will work with earlier versions these are recommend because of the improvements that were implemented with the new Image Process in Camera Raw. Trial versions are available for download from Adobe. In case you are wondering about cost, the normal cost for this fine package is $10, however if you use the code “DODGE8” during checkout, it will only be $8. This is only for a limited time, so go and get the Dodge&Burn ebook through this link and use the code before midnight on July 22, 2012. The Craft and Vision book store also has a package deal, for the same limited time, in which you can get 20% off 5+ ebooks from the site, the code is “DODGE20”.  All of the books are worthwhile, however I recommend in addition to the Dodge&Burn, ebook to take a look at Up Close, Exposure for Outdoor Photography, Making the Print, and the Power of Black and White. There are many others that are excellent but those will give you some great information.

So be sure to check out the ebook, and learn how to Dodge and Burn effectively, bring up those shadows and modify the highlights to match your initial vision when you took the picture.  This is an art that does take practice and there is certainly many ways to accomplish the same effects but this book will give you a great start and some insight into improving your images. Not only are the traditional type of modifications discussed but also uses of sharpening, and tonal effects to add some depth to your vision. How to effectively do it in a non-destructive fashion in photoshop, but also how to use some of the tools from Nik Software as a way of making it more efficient.
