Canon EOS-1Ds: Highly Recommended by dpreview.com
Read the full Canon EOS-1Ds Mark III  review at dpreview.com.
First an apology; the Canon EOS-1Ds Mark III arrived in our office well over eight months ago (when we were 'between studios') and, though we've been using it regularly every since, the avalanche of digital SLRs that arrived in January caused this review to be bumped down the queue so often that it started to develop a persecution complex.

This is because, although there's no doubt that the Mark III sets the standard for digital SLR resolution and significantly narrows the gap between '35mm format' and 'medium format' digital cameras, it is also undoubtedly a niche product that will, by now, have been bought (or earmarked for purchase) by pretty much everyone who is ever likely to hand over the best part of $8000 for one.

An entirely new 21.1-megapixel full-frame Canon CMOS sensor delivers astounding image quality and creates new photographic possibilities. Dual "DIGIC III" Image Processors work in tandem to speed up data handling and camera operation, while further refining imaging performance. Tough, high-durability body and shutter designs, combined with the unique EOS Integrated Cleaning System, set new standards for professional dependability. Cutting-edge features-such as a large 3.0-inch LCD monitor with Live View Function, and a fast, precise 45-point AF system-make the EOS-1Ds Mark III powerful and versatile. And, of course, the EOS-1Ds Mark III is part of the unparalleled EOS System, which, with more than 50 EF lenses, 15 interchangeable focusing screens, and extensive wireless remote control and lighting accessories, is the most advanced and powerful digital photography system in the world.

Canon EOS-1Ds Mark III Highlights

Superb Image Quality

The EOS-1Ds Mark III incorporates Canon's newest CMOS sensor, which delivers approximately 21.1 effective megapixels (5,632 x 3,750 pixels). The recording area of the sensor is 36 x 24mm, which is equivalent to the full-frame size of the 35mm film format. The tremendous pixel count delivers high-resolution images of exacting precision, with Photoshop file sizes over 60MB for outstanding quality at large print sizes and post-processing cropping flexibility. Despite the higher pixel density, Canon CMOS sensor technology ensures exceptionally low noise and the widest usable ISO range* (from 50 to 3200, using ISO range extension).

Highlight Tone Priority
Activated via a Custom Function on the EOS-1Ds Mark III, the unique Highlight Tone Priority feature takes full advantage of the camera's 14-bit per channel digital conversion to provide smoother gradations from the grays to the highlights and preserve greater detail in image highlight areas — a perennial problem for digital photographers, especially those who work in bright sunlight or contrasty studio lighting. Highlight Tone Priority expands the available range of capture in the highlights, yet it exacts no penalties in either shadow detail or other aspects of image capture.

Image-Processing Sequence Diagram
Advanced 14-bit A/D Conversion
Whereas most other digital cameras use 12-bit A/D (analog-to-digital) converters, the EOS-1Ds Mark III employs superior 14-bit per channel converters to process the output of the imaging sensor. In each color channel, this means there are 16,384 distinct brightness steps from the darkest to brightest tone (vs. 4,096 previously). This ensures smoother tonal transitions and more natural gradations. RAW images are recorded at the full 14 bit, and once processed will preserve the entire range of tones when opened in Photoshop's 16-bit color space.

"Picture Style" settings
With another great feature, Picture Style technology, photographers can recreate characteristics of their favorite films. Color, saturation, sharpness and contrast settings create noticeable variation in the saved image. In addition to six preset Picture Style settings (Standard, Portrait, Landscape, Neutral, Faithful and Monochrome), users can create three additional settings for their particular photographic style.

Picture Style settings are applied directly to JPEG images, giving tremendous flexibility to shooters who prefer the ease of JPEG files. If RAW images are processed in Canon's Digital Photo Professional software (v. 3.2 or higher) or RAW Image Task software, the versatile Picture Style settings can be modified or completely changed in the computer, without affecting the original file.

Dual "DIGIC III" Image Processor for excellent image quality and processing speed. spacer

Dual "DIGIC III" Image Processors
Dual DIGIC III Image Processor
Developed to maximize performance between the capture and recording stages of digital photography, the EOS-1Ds Mark III's Dual "DIGIC III" Image Processors work in parallel to dramatically enhance image quality and deliver the speed and power needed to combine 21.1 million pixels and 5 frames per second. The latest-generation DIGIC III Image Processor works in concert with Canon's CMOS sensor to achieve even higher levels of performance. The entire electronic system is totally re-designed, giving the camera its incredible combination of speed and image quality. Digital noise is significantly reduced in shadow areas, and color reproduction is superior.

Live View Function capabilities, displayed on the large 3.0-inch LCD monitor. spacer The EOS-1Ds Mark III features a sophisticated Live View Function, which makes the LCD monitor a real-time finder. When the Live View Function is enabled, the reflex mirror is locked up and the shutter opens. The image output from the CMOS sensor will be displayed in real time on the LCD monitor with 100 percent coverage. A selectable portion of the image can be magnified by 5x or 10x to aid in precise manual focusing. Focus, exposure check, composing, and shooting can all be accomplished in this mode. There is also a grid overlay option, perfect for architectural photography.

Live View Function is convenient for tripod-mounted shooting, macro work, precise shooting with Canon's Tilt-Shift lenses, and many other situations in which it is a physical strain to keep the eye at the viewfinder. The image can also be displayed on a TV monitor, which is ideal for showing photographs, as they are being composed, to clients and portrait subjects.

Canon's Remote Control Software Screen (EOS Utility software)
Remote Live View Function
Using Canon EOS Utility software, photographers can check and adjust focus and composition in real time on their personal computers, whether in the studio or on location. The camera can even be fired remotely from the computer. Connection between the camera and computer can be done via USB cable or, with the optional WFT-E2A Wireless Transmitter, via wireless LAN or an Ethernet connection.

Outstanding durability thanks to a shutter durability-tested to 300,000 cycles, dust- and water-resistant design, and EOS Integrated Cleaning System

Unprecedented shutter durability
The EOS-1Ds Mark III features an improved heavy-duty shutter that has been durability tested to 300,000 cycles. The camera thus provides long service life and inspires the all-important confidence for the professional that comes from the knowledge that the shutter will perform on demand.


Canon EOS 1Ds digital SLR highlights
Location of Major Water-Resistant Measures
Weather-Resistant Design
Extensive weatherproofing ensures superior reliability, even when shooting in harsh environments. Rubber gaskets are used at nearly every joint and seam--including around the battery compartment cover, memory card door, and flash shoe--to keep out moisture and dust.

EOS Integrated Cleaning System
Photographers who must change lenses in dusty environments will find the advanced Canon EOS Integrated Cleaning System a tremendous time saver. Dust that settles on the low-pass filter is removed using ultrasonic vibration. This Self Cleaning Sensor Unit is automatically activated whenever the camera is powered on or off. (It can also be manually activated.) A special collar positioned around the sensor collects the loosened dust. Dust particles can also be automatically removed via software. By shooting a plain white subject, the photographer can acquire dust position data called "Dust Delete Data" that is transmitted along with each subsequent image (whether JPEG or RAW). Canon Digital Photo Professional (DPP) v.3.2 or higher software can then be used to manually or automatically erase the dust spots, before the image ever gets to Photoshop or a similar image-editing program.

Dust that has been missed by the Integrated Self-Cleaning Sensor Unit can also be erased with software included in Digital Photo Professional (DPP) Version 3.2 or higher. The EOS-1Ds Mark III's imaging sensor is able to single out the dust particles on its surface, then plots out their location coordinates within the image. This data is transmitted along with the image, whether JPEG or RAW, and can be either manually or automatically erased in Canon's DPP software. This added software option ensures the cleanest possible image, perfect for printing or archiving.

This added software option ensures the cleanest possible image, perfect for printing or archiving.

Up to 5 fps, burst rate up to 12 consecutive RAW images or 56 full-resolution JPEGs

Impressive Shooting Performance
The new 21.1-megapixel full-frame CMOS sensor generates a tremendous volume of data that must be processed by the camera. Thanks to unparalleled Canon high-speed data management technologies--including the use of dual DIGIC III processor chips--the EOS-1Ds Mark III delivers full-resolution performance without sacrificing all-important shooting speed or camera responsiveness. Maximum continuous shooting is 5 fps, and up to 56 consecutive full-resolution JPEG or 12 RAW images can be captured in a single continuous burst (at shooting speeds up to the full 5 fps).

Compatible with UDMA CF Cards
The EOS-1Ds Mark III supports the latest, faster UDMA (Ultra Direct Memory Access) CF memory cards. UDMA-compliant CF cards offer twice the data transfer rate of conventional cards, further enhancing the shooting and post-shooting performance of the EOS-1Ds Mark III.

Fast and precise AF system

The EOS-1Ds Mark III incorporates new Canon AF technologies that bring about improvement in key performance areas. The extraordinary 45-point high-density area AF system provides not only the industry's largest continuous AF coverage area, but also the greatest range of control over focusing point selection. The focusing point can be selected automatically by the camera (based on high-speed microcomputer analysis of image content), or users can manually select any of the 19 high precision cross-type AF points, which can be complemented by 26 additional Assist Points for fast, accurate focusing.
Canon EOS 1Ds digital SLR highlights


A separate processing unit devoted solely to autofocus calculation is a key in the EOS-1Ds Mark III's superb AF performance. The One-Shot AF mode is ideal for more static subjects. The camera rapidly selects the optimum focusing point, and the subject is instantly brought into focus even if it is off-center. The AI Servo AF mode is excellent for moving subjects. Aided by a the camera's outstanding new AF sensor and powerful processing abilities, it precisely tracks subject movement, even when shooting continuously at 5 fps. Even with erratic or rapid subject movement, the photographer can concentrate solely on image composition.

New Custom Functions aid the photographer in choosing default focusing points, as well as changing the size of a manually-selected AF point, making this not only the fastest, but also the most customizable AF system on the planet.

Compatible with wireless file transmitter WFT-E2A, extensive remote control accessories, and 15 different interchangeable Ec-series focus screens. spacer

Wireless File Transmitter WFT-E2A
A significant redesign of Canon's earlier wireless transmitter, the new WFT-E2A is much more compact and provides a broader range of useful professional functions. It integrates elegantly with the EOS-1Ds Mark III, is powered by the camera body, and is as durable and weather-resistant as the camera itself. Not only can the camera's files be sent to a compatible computer in three different wireless modes, but you can even remote-control the camera, wirelessly, from your computer.

The WFT-E2A can be easily set up to operate in wireless LAN (802.11b or g) environments. A new, more efficient built-in antenna enables wireless communication with host computers or access points up to 492 ft./150m) away. Where wireless access is limited, the WFT-E2A can be used for conventional (wired) Ethernet connection.

USB 2.0 Hi-Speed host capability enables the use of external storage media, such as a USB hard drive, for memory card backup, quick copying of files, or just vastly expanded shooting capacity. Images shot on the camera can be recorded directly to the hard drive. The WFT-E2A can also communicate with various third-party GPS devices connected via USB. Location coordinates, precise Universal Time Code, and altitude can be sent to the camera and added to each image's original shooting data.

Interchangeable Focusing Screens
The EOS-1Ds Mark III is equipped with the Laser Matte Ec-C IV focusing screen, which provides superior optical performance. Background blur appears more natural, and graininess and flare are reduced. At the same time, the finder is brighter, especially at the edges and corners. As with all EOS-1 Series SLRs, the EOS-1Ds Mark III gives a photographer the widest choice of interchangeable focusing screens. Currently, there are 15 different Ec-series screens.

EF Lenses
Of course the EOS-1Ds Mark III is compatible with all Canon lenses in the EF lineup, ranging from ultra-wide angle to super telephoto lenses. Canon lenses employ advanced optical expertise and micron-precision engineering to deliver unprecedented performance in all facets of the photographic process. Special optical technologies, such as aspherical optics and fluorite elements are featured in the universally acclaimed L Series lenses. A new addition to the L Series is the EF 14mm f/2.8L II USM lens. With a 114° angle of view that can be captured with the EOS-1Ds Mark III's full-frame sensor. Unlike a fisheye lens, this stunning new ultra-wide lens is totally corrected for linear distortion, and offers even better sharpness and contrast than its predecessor, Through Canon lenses, photographers can truly maximize the quality and liberating performance of the EOS-1Ds Mark III.

Flash Photography
The EOS-1Ds Mark III features the acclaimed E-TTL II flash metering system. With any of the flashes in the EX Speedlite line, E-TTL II provides reliable flash output whether shooting fill-in flash pictures in sunlight, or using flash in total darkness. The camera's new 63-zone evaluative metering sensor is also used for flash metering -- giving even finer metering command of the image area. If you prefer a broader area for flash metering, Custom Function II-4-1 allows shifting flash metering so that all 63 zones of the sensor are used equally to calculate flash exposures.

Canon's Speedlite 580EX II is perfectly suited to the EOS-1Ds Mark III. It has improved reliability of communications through the direct contacts, has a metal flash "foot," and is dust- and water-resistant as with the EOS-1Ds Mark III. Other new features include a PC socket on the flash unit, and an external metering sensor for non-TTL auto flash if desired. With the EOS-1Ds Mark III, you can set most flash settings directly from the camera's menus. It has the same power as the previous Speedlite 580EX (maximum guide number of 190 ft./58m at ISO 100), and with its built-in wide panel, can be used with lenses as wide as 14mm on Canon's full-frame cameras. It includes an AF-assist Beam, which works in conjunction with the EOS-1Ds Mark III's focusing system, and automatically sends color temperature information to the camera when the flash fires, for more accurate white balance rendition with flash photography.

Software

Canon's EOS Digital Solution Disk (Version 15.0) features powerful software programs designed to extend the EOS experience to the computer. These include Canon's ZoomBrowser EX for Windows® (Version 5.8), ImageBrower for Macintosh® OS X (Version 5.8), Digital Photo Professional (Version 3.2), Canon's EOS Utility (Version 2.0), RAW Image Task (Version 2.6), PhotoStitch, and PTP TWAIN Driver. Each application is designed to perfect captured images and streamline the digital workflow. ZoomBrowser EX v. 5.8 and Digital Photo Professional v. 3.0 for Windows are compatible with the new Windows Vista operating system, too.

Digital Photo Professional (Version 3.2) is an image processing program that enables high-speed RAW image processing, high-speed previewing for real-time image adjustment and support for sRGB, Adobe RGB and Wide Gamut RGB color spaces. Because it's CMS (Color Management System) compatible, Digital Photo Professional allows for easy image layout and printing in Adobe RGB in conjunction with Easy-PhotoPrint and PictBridge printers. It also features the Dust Delete Data Detection tool for cleaner images.

EOS Utility (Version 2.0) for Macintosh or Windows handles the connection between the camera and computer, whenever they're connected via USB. It allows remote controlled shooting from the computer, handles downloading of images from the camera to the computer, and allows seamless linking to either Canon's ZoomBrowser/ImageBrowser or Digital Photo Professional software once images have been copied to the hard drive. Furthermore, it's used to upload settings back into a USB-connected camera.

ZoomBrowser EX (Version 5.8) for Windows and ImageBrowser (Version 5.8) for Mac OS X are the easy, user-friendly options for viewing and editing of JPEG and even RAW image files. Both allow viewing of numerous types of images including finished TIFF and BMP files. Both also have a variety of search options for finding images, allow re-naming of single images or batches of files, and offer a variety of options for printing without using a separate image-editing program.

RAW Image Task (Version 2.6) is an integrated component of ZoomBrowser EX (Windows) or ImageBrowser (Mac). It allows processing of RAW images from EOS cameras, including the new EOS-1D Mark III, with a variety of adjustment possibilities. These options, as well as the overall color, contrast and "look" of RAW Image Task, closely mimic the characteristics of Canon's in-camera JPEG processing.

5.0 out of 5 stars Best DSLR on the market January 21, 2008
Well if you are looking at this fine piece of Photographic equipment odds are you have been to the Canon website and read the specs. I will touch on a few of the items I have noticed since I purchased mine and have been using it.

1st. The feel, just like the 1D M3, this beast is solid. Not too heavy, but solid in the hand. And here in Alaska, I do put the weather sealing to a test, and just like my trusty 1D M3, the 1Ds passes with flying colors.

2nd. Yes its 21.1 MP, but that should not be your main consideration to buy it. Yah 18x12 @ 300Dpi out of the Camera is nice, but nost people dont print over 16x20, and I have sold a lot of prints from my old 20D at that size or even upto 20x30, as long as you shoot it right in the first place. But this is also a drawback as well. Because of the large file size, esp in Raw, and most, if not all, buyers of this body will/should be shooting in raw, be aware that you will need larger CF cards for it. At least 8gig, I use 12Gig for mine, extreme 3's and they work great! Also be aware if you use the internal high iso noise processing, it slows down the buffering a lot!!!

3rd. Full Frame, just like the earlier 1Ds models its a ful frame sensor. That means 2 things, not only does a 17mm or 14mm lens again be a true wide angle lens, but also with the larger sensor the pixels are more refined and this gives better color and less grain.

4th. The colors of the images in the files. WOW Again the 14bit processors are great!!! Esp for raw, where you can import it in as 16bit for the finer details. One draw back is if you use Photoshop, you will need CS3 to do the raw Conversions, unless you use the Canon program.

5th. You are approaching the image quality of a Dig MF camera, with the portability of a Dslr! Not to mention you can use all the Canon EF lenses, and this camera really should only be used with L series lenses when possible, except for the fisheye as its not made in an L series but the quality is very good anyways. As the Quality of the optics is what affects the quality of the image the most, other than settings in the camera, ie shutterspeed and AV, ISO, etc...

6th. Wonderful Accesories for the camera. I love my wft-e2a. I use it on my 1D M3 a lot and it works great on the 1ds as well. Its a great way to control your camera remotely or to send your files to a remote computer for processing and such while you are still shooting.

This Camera is great. I have used the new nikon d3, and its a much improved camera over the past models, but it does not compare to the top of the line Canon!!!! This camera will not let you down. The noise if shot right is not even noticed until iso 1600 and then you still got to look. ISO 3200 is still great (about the same noise/grain my buddy had on his d200 at iso 400!!!!!)! If you are a Pro and need a camera that can perform the best and give wonderful results, this is it. It kicks butt compared to anything else in the DSLR market!!!

5.0 out of 5 stars Wonderful professional camera February 24, 2009
I owned this camera since spring of 2008,
So at the point of writing this review, I used it for nearly a year.

Now, if you are earlier owner, you might have experienced a problem or two.
I was unfortunately one of the owner experienced problem, and had to ship it back to Canon for the warranty repair. So, I was not exactly happy about paying expensive FEDEX freight.

But, rest assured, no other nasty problem occurred after warranty repair, and this camera has been workhorse of my photography.

Now, let get on the review.

This is really wonderful 21.1MP camera, and it is well worth the money.
But, you have to determine if you need to use one.

At the time of release, there were no other full size sensor camera with this resolutions.
Of course, it has been since passed by other manufacture... but I will not going to that comparison.

For Professional User.

Important thing about this camera is economics.

I own EOS 5D as well, and when non-commissioned or low paid project, I tend to bring 5D instead of 1DS MK3.
It is due to the fact, overall operational cost tend to be higher on the 1DS MK3 so if does not paid well, there will be no point to bring it out.

But, if it does paid well. there are enough justification to own this system, and you should used it as much as you can.

And this system is really reliable, once you get past some getting used to.

One more note,

Now I do own several different system including Hasselblad Medium format.
Medium Format Digital System is superior system when you are working in the control lighting environment. However, it is rather difficult to work with in the outside activity.

If you are studio photographer with magazine or commercial client, and do occasional out side shoot, you should own both medium format and this camera.

If you are professional just wondering about medium format and full size sensor camera,but without pressing need, then do not bother with medium format.

People who uses medium format digital normally has pressing reason such as satisfying client's specifications to own such system.
And it is not really versatile system no matter how medium format camera maker and digital back manufacture portray.

Canon 1DS MK3 is really versatile system, and it will satisfy most of design agency, publisher or stock photo agency's requirement, and L lens system are reasonably priced for the performance when looking at the economics.

For Semi Pro or High Amateurs User

For semi professional. 1DS MK3 is not going to make best economic argument, if you do not shoot studio.
If you are part time photographer who shoots mainly events or doing photo journalism.
I will recommend 1DMK3 over 1DSMK3.

Also, for photo journalist purpose, nowadays 5D MK2 actually makes a lot more sense than getting 1DS MK3 due to the their HD capability.
And for the photo journalist, it is not that good idea to carry bulky system.

But, for an amateur user with a lot of spending money,

It is one of the best system to get taste of what real pro are using.
And it does not cost like price of new BMW, and for the financially resourceful amateur, 7 to 8 grand may not be much of money.

When I got 1DS MK3 there were several amateur photographer I taught how to use this camera...
Surprising thing is, there are quiet many of amateur owner, and with very limited instruction to them,
They were able to create very good quality images.

So, kudos to the Canon for new 1DS MK3 interface.
It is actually easier for 1DS first timer than older 1DS MK2 for instance.

Of course, people who were used to with 1DS MK2 or older tend to disagree on this.

Now here are list of main advantage.

1. It is 21.1MP, more than most of commercial assignment requires.

2. Color depth of 14bit per channel is really useful for RAW work flow process.

3. Economical compared to the expensive medium format system, and still get comparable or sometimes superior result if conditions are right.

4. Build like tank, and it can take a quiet bit of abuse.

5. For user who are used to with 20D~50D, 5D MK1~MK2, it is really easy to learn interface.

6. Dust cleaning is really useful.

7. AF + Canon L Lens combinations is superior to the other known system in the market as of 2008-9

8. Liveview is useful to shoot architecture, land scape, and products.

9. RAW file format is supported well by the major commercial software.

10.CF slot and SDHC slot actually helps. It did not occurred to me until I run out of memory card on the locations, and had to run to the nearby local drug store. At least they carry cheap SD/SDHC at any large drug store chains, and it is a lot easier to find those store than locating nearby large electronic store...

11. Battery Life is excellent, it will easily cover half day events with nearly a thousand of picture even with taxing RAW + JPEG shoot.

12. Due to its weight and form factor, it is a lot easier to balance with long heavy lens.

13. When used with L lens, it is somewhat comparable with expensive medium format digital back.

14. Silent shutter mode is somewhat useful.

Now here are list of disadvantage.

1. It is slightly new form factor for Canon, and there are chance you had to send it to the warranty repair if you got the earlier production model.

2.There are something wrong with design of wireless port cap. It is relatively easy to lose one since it sometimes fell off with limited torque applied. I lost several of them already... though I stocked half dozen cap after I lost my first cap.

3. It is heavy and bulky. Thus some times not a ideal for certain situations.

4. Compared to Nikon D3X, it has slightly poor SNR on the third party software RAW processing software, so certain journalistic style shoot might suffer. If you shoot in the studio controlled lighting environment, that should not be a much of issue.

5. Many of RAW development software is actually more well tuned for Nikon, This might to be due to the amount of info Canon release to the third party software developer.

6. It is hard to justify its price for the many of users.

7. However everyone else claimed, it still can not replace medium format digital camera. Lens resolution and clarity of images is not there yet. Of course, that is when looking at 1:1 images side by side.

8. Silent shutter mode is not that quiet compared to some of the most quiet camera in the market. So, application such as close quarter Jazz or Classical music shot are still off the table.

Overall, I will recommend this camera to who,

If you are photographer that shoot tons of weddings at high fee structure, you should get one. Otherwise, EOS 5D nowadays makes very attractive choice.

If you are commercial photographer with clients and sufficient invest in Canon system, why are you waiting?

If you are amateur with deep pockets, this is a camera to get, and impress your photography teacher!

I will not recommend to someone,

Trek photographer who need lighter weight gear or those wild life photographer needs of faster fps should consider other offering from Canon.

Any journalistic style should consider 1D MK3 first unless you shoot tons of interview photo.

Shooting for hobby or fine arts purpose should really consider 5D mk2 before taking financial plunge of 1DS MK3

If you think it is heavy for you, do not get it. It will be too heavy for you after few hours of holding camera.

5.0 out of 5 stars The Revolution Continues January 16, 2008
In every way Canon has done it again. This camera is lighter, faster, and produces bigger, better files than the mk2. If you make a living shooting pictures, buy it, you may never have to upgrade again. If Photography is your hobby or passion and you can afford it this should be your last camera.

My five favorite improvements in no particular order.

Faster and more accurate autofocus

Less noise at high ISO making 3200 a viable choice.

File quality that beats many 22MP medium format digital backs.

Live preview, it's cool, fun, and useful.

Improved handling due to lighter more balanced feel

Yes I know number three will get me in trouble but the price, faster handling, and much broader lens selection make it great choice in the 22 to 30MP range. The 39MP backs are clearly more detailed and smoother but this Canon will push many a P25 and H3D-22 onto ebay in the next year.

Canon has set the standard again the mk3 is truly brilliant. The only better deal may be the well cared for used mk2's easily found on ebay.

I just wanted to add a comment regarding cost. Now that my second mk2 has found a new home I can evaluate the true cost of an $8000.00 dslr. I paid $7300.00 each for my mk2s. Sold them for an average of $3620.00 making the cost if you add in an extra battery and firewire cables for three years around $4000.00 each. I anticipate this kind of return for the mk3s and considering they will work in a high demand professional environment for three years or so I'd say the mk3 is a ridiculous bargain.

By the way both of my mk3s have performed flawlessly and were spot on with regards to viewfinder alignment.

5.0 out of 5 stars Exceded my Expectations
Paired with the 24-70mm f2.4 L this is perfect for portraits. I can't imagine the picture quality with the 80mm L lens but, it must be extremely amazing.
