From the Manufacturer
It's All in the Detail
With all the features and capabilities of the EOS 5DS, the EOS 5DS R camera offers the potential for even greater sharpness and fine detail for specialized situations. It features the same Canon designed and manufactured 50.6 Megapixel sensor, with the low-pass filter* (LPF) effect cancelled to provide even more fine edge sharpness and detail for critical subjects such as detailed landscapes, and other situations where getting the sharpest subject detail is a priority.
* The possibility of moiré and color artifacts is greater due to the LPF cancellation function.
The EOS 5DS R camera has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be offered for sale or lease, or sold or leased, until authorization is obtained.
Spectacular Resolution for Specialized Applications
Low-pass filter effect cancellation
For photographers wanting the ultimate in high resolution capture, the EOS 5DS R camera has a low-pass filter* (LPF) effect cancellation. While a low-pass filter is useful to reduce color artifacts and moiré typical with digital capture, it also reduces detail at the pixel level. With the LPF disabled, the EOS 5DS R takes full advantage of the original resolving power of the camera's 50.6 Megapixel sensor. More detail is captured and retained in the original image, perfect for landscape and commercial applications where pixel-level detail is scrutinized and when the sharpest possible image is needed.
*The possibility of moiré and color artifacts is greater due to the LPF cancellation function.
More Resolution for Bigger Images
New 50.6 Megapixel Full-frame CMOS sensor
The EOS 5DS R camera features Canon's newest full-frame CMOS sensor. At 50.6 Megapixels, it's the highest resolution sensor in the history of EOS. It captures 8712 x 5813 effective pixels, delivering images with an unprecedented level of realism perfect for large-scale commercial printing, fine art, significant crops and any number of other high end applications. Thanks to this amazing sensor, engineered to work in concert with dual DIGIC 6 Image processors, the EOS 5DS R is a remarkable, high-resolution camera with impressive performance.
New Fine Detail mode in Picture Style
Taking advantage of its sensor's high-resolution capturing power, the EOS 5DS R camera has a new Picture Style called Fine Detail mode. Fine Detail emphasizes fine edges and patterns or textures by setting the camera's Sharpness sub-settings, fineness and threshold to their minimum and by lowering contrast settings as well. Prioritizing minute details in the image allows for better gradations, more detailed textures and fine edges for smoother, more polished photographs.
Speed and Accuracy with Intelligent Scene Recognition and Analysis
EOS Scene Detection System with RGB+IR Metering Sensor
The EOS 5DS R camera has an amazing iSA Intelligent Scene Analysis system that employs an independent RGB+IR light sensor with approximately 150,000-pixel resolution. This sensor enables Canon's Intelligent Tracking and Recognition system (iTR AF) that detects and tracks subjects, automatically switching the AF point to optimize tracking. With new tracking algorithms tailored to recognize faces and colors, this system serves as a brilliant foundation to the EOS 5DS R's AF system.
Precise and Fast AF for High Resolution Detail
61-point High Density Reticular AF
For fast, precise AF with sophisticated tracking performance, the EOS 5DS R camera has an advanced, 61-point High Density Reticular AF system with up to 41 cross-type AF points. The EOS 5DS R's AF system is incredibly sensitive to changes in composition, making adjustments quickly to help ensure consistent, sharp AF. A new RGB+IR AF (with approximately 150,000 pixels) sensor monitors subject motion, and Canon's iTR Intelligent Tracking and Recognition system synchronizes the active AF point with the subject's motion, helping to ensure that AF precision is maintained. With focus modes dedicated to the particulars of the shooting environment, the EOS 5DS R realizes a level of focus accuracy befitting its 50.6 Megapixel sensor.
Mirror Vibration Control for Sharper images
Advanced Mirror control mechanism and shutter release time lag
The camera shake that occurs from the impact of an SLR's mirror can leave blurred details in the recorded image. This effect is magnified when working with a super high-resolution sensor like the one found in the EOS 5DS R camera. To counter the effects of conventional, spring-driven SLR mirrors, the EOS 5DS R features a newly developed Mirror Vibration Control system. The camera's mirror is not controlled by springs but instead is driven by a small motor and cams. This system suppresses the impact typical of the camera's mirror, significantly reducing impact and its effects on the image. A new Time Release Lag setting, easily accessed on the EOS 5DS R's menu system offers added protection against camera-shake blur by setting the shutter release time intentionally longer so the camera does not begin the exposure until after the impact of the camera's mirror has diffused.
Better Accuracy in More Situations
With Canon's Anti-flicker function, the EOS 5DS R camera is able to deliver accurate results under cycling lighting situations. Under flickering light, such as fluorescent lighting, a fast shutter speed may result in an irregular exposure. The EOS 5DS R's Anti-flicker function detects the frequency and phase of the flicker and captures images near the point of peak brightness when the subject is most likely well illuminated.
Specialty Controls, Built Right In
Built-in intervalometer and bulb timer
The EOS 5DS R camera offers time-lapse fixed-point shooting and long exposures without the need for a remote control. The EOS 5DS R's interval timer takes from 1 to 99 shots at preselected intervals (from 1 second to 99 hours 59 minutes 59 seconds, or unlimited), ideal for shooting flowers as they bloom or clouds drifting through the sky. Captured exposures can even be collected and saved as an HD movie. Its built-in bulb timer keeps the shutter open for a designated amount of time, perfect for night photography, to capture the flow of traffic on a street corner, or any other situation where long exposure photography is warranted.
Simple Cropped Shooting, In Camera
1.3x and 1.6x crop shooting
For still photography, the EOS 5DS R camera features the flexibility of a cropping feature that extends the shooting effect 1.3x and 1.6x. With 50.6 Megapixel capture, cropped shots are possible with plenty of resolution to spare. Images recorded at 1.3x (APS-H) are approximately 30.5 Megapixels (6768 x 4512) Large/Fine JPEG, while images recorded at 1.6x (APS-C) are approximately 19.6 Megapixels (5424 x 3616) Large/Fine JPEG. Particularly useful in extending the range of telephoto lenses, the crop function also improves the EOS 5DS R's subject tracking capability with almost the entire frame covered with AF points. Image cropping can be displayed in the viewfinder either masked or overlaid with an outline showing the cropped area, and in Live View shooting the image is cropped by the effect chosen. Aspect ratios can also be defined, with the EOS 5DS R shooting in 1:1, 4:3, and 16:9 ratios, in addition to the default 3:2.
Comprehensive Information, Right in the Viewfinder
Intelligent Viewfinder II
The EOS 5DS R camera's Intelligent Viewfinder II makes it easy to both shoot, change and confirm camera settings and shooting modes all without looking away from the viewfinder. Displaying approximately 100% of the composition, the viewfinder can show settings like shooting mode, exposure level, white balance, drive mode, AF operation, metering mode, recording format, an electronic level and more. All of this information can be displayed by or superimposed easily over the image for review while shooting, and multiple views are customizable through the EOS 5DS R's simple user interface.
Sophisticated Moviemaking with EOS
Full HD 30p movie capability
The EOS 5DS R camera is a sophisticated movie-making machine, capturing full HD movies with numerous manual controls at multiple frame rates and compressions. Featuring movie capture and manual controls befitting a flagship camera, the EOS 5DS R's shutter button can be programmed to capture still images when pressed during movie shooting.

Top customer reviews
There was a problem filtering reviews right now. Please try again later.
1) The build and feel is 99% identical to a 5D3, which is fantastic ergonomically, and experienced Canon shooters will feel right at home with this one. It's solid, study. weather sealed, and the mode dial got a nice little upgrade with raised icons and what seems like a bit more solid grip. The new LPE6N battery provides longer life but I'm using my old LPE6 (standard) in it just fine right now. Dual Digic 6 chip do suck up a lot of juice.
2) The lag time between the shutter and the jpg preview popping up on the rear LCD is a little longer than the 5D3, but that's to be expected as we're talking 70MB RAW files here. Yes, 70MB.
3) Speaking of the shutter, the sexiest thing about this camera (besides the red "R") is the new shutter and it's new sound. It's like a sniper rifle with a silencer. It's very stealth and sleek with it's new all motor driven mechanism (as opposed to the old standard motor lift and spring return). By the way, the RGB+IR metering system they brought down from the 1DX for this? Awesome. Love it. I feel like the metering has been more accurate than my 5D3, and I've even used the 1DX many times myself.
4) I've been handheld shooting with a Canon 135 f2 L. First of all, what a lethal combo with this new 5DSR. Wow. Resolution is off the charts good. I found handheld shooting certainly requires a bit more care than the 5D3 to get the most out of the sensor, but we all knew that going in. This is a studio/tripod loving camera. HOWEVER, you can get really good results going about 4-5 times focal length with your shutter speed. (50mm lens x 5 = 1/250th second). Of course, having IS on your lens really helps. By the way, add "Mirror LockUp" to your custom menu (the green tabs). This way you can go in quickly and alter your shutter release lag time if need be, which is precisely why they built the new shutter. That way, you press the button, and the mirror flips up and the camera waits anywhere from 1/8 to 1 second before dropping the curtains on the sensor. You can set it in that range or just turn it off, or engage traditional old manual mirror lock up with the first button press lifting the mirror and the second button press dropping the curtains.
5) I can't get this thing to Moire. I have deliberately shot some really small fabric patterns and weaves, brickwalls, so on and so forth, I can't get it to create the negative artifact. Without the Low Pass Filter effect (this camera has TWO LFPs that cancel each other out to raise sharpness) the propensity for generating Moire and Aliasing goes up.... THAT SAID, at 50MP even the smallest details can get resolved well, so artifacts don't really seem to be a problem so far. Now I know I have some dancers I shoot that wear silky shiny dresses with tight fabric weaves and I suspect I may encounter some color moire there. However... Lightroom's Moire tool does a really good job to easily and quickly remove it if need be.
6) This is NOT NOT NOT a general use, everyday camera. Please get a Canon 5D Mark III (5D3) for that or the amazing 6D for half the price of 5D3. The 5DS and 5DSR really are for professionals who need the ultra high resolving capabilities for a variety of reasons such as Large Print work, studio work, pictures of large groups, architecture and landscapes, and the ability to shoot wide and crop in post without losing details. You don't want to buy this camera to take family pictures. It's overkill and the file sizes, as I mentioned before, are enormous. I own both the 5D3 and 6D. Both are excellent cameras and both are excellent general purpose cameras.
7) Buy Glass. Don't buy this camera expecting the world from even your 24-105 F4 L lens. I have one. Good lens. 5DSR DOES make it look better than on a 5D3... BUT, if you really want to take advantage of what this machine can do, you need to look into some of the upper level L glass like the the new 16-35 f4 L or the 70-200 f2.8 IS II. The 135 f2 L is STILL one of the sharpest lenses ever made and looks gorgeous on this, as do the new Sigma ART lenses. (Everything I just mentioned, I own and have shot on this 5DSR now)
8) ISO performance - Ok it's a studio and landscape camera. It's meant to be shot at or near base ISO, right? (100-800). Well last night I shot a bunch of stuff in my house handheld at 6400 ISO. Lemme tell ya... It looks...really....nice. For all the flak on how much this camera would suck at higher ISOs I think it looks no worse than a 5D3 and maybe even a bit better (again, mostly dependent on your technique.) I would suggest as I always do with higher ISO... ETTR. Expose To The Right. Push your camera exposure compensation UP one stop and pull back highlights in post if need be. I think the 5DSR images at 6400 are really very clean for that sensitivity, but everyone has their own personal feelings about what is "usable" Not here to debate. That's just me. I'd put the 6400 ISO performance on par with a 6D. I'm perfectly happy with it.
9) If you're a pro who needs the juice. Buy this. You will not regret it. It's an excellent and well built professional tool. I can't wait to do a REAL studio test with this. I will update as I do.
UPDATE: 6/24 - Posting pictures shot with this seems futile given how images are compressed to post on the review, but here ya go: (Handheld shot using the Canon 16-35 f4 L on the Boat and Canon 135 f2 L on the girl)
UPDATE: 6/26 - I have run across an owner or two who have gotten very minute amounts of Moire in some extreme situations (wildlife in this case). But nothing that wasn't quickly corrected in Lightroom without any damage to the image quality. That said, I still have not had the issue. It confirms my second thoughts when I cancelled my initial order of the 5DS in favor of the 5DSR
UPDATE 7/14 - First studio shoot last weekend was a big success so far as I'm concerned. Was amazed by how much detail was retained on the face and hair even from half and full length poses. Headshots were amazing. EVen though you tend to soften the skin in post, the ultra fine details you can retain where you really want to keep it (eyes, eyelashes, eyebrows, hair, etc) is uncanny. Very happy with the results. It's being able to crop in and turn a wider shot into headshot and still have the same resolution in so doing as I would had I just taken a headshot with the 5D3. Loads of flexibility!!!
UPDATE 7/21 - Someone posted a good question about the contrast and saturation compared to other popular current Canon models like the 5D3. Yes, contrast and particularly color saturation seem to be more and richer. Canon previously stated months ago that this camera would be using a better CFA (Color Filter Array) more akin to those of the vaunted and still loved Canon 1Ds III. I just two days ago did direct comparisons between the 5D3 and 5DSR and concur this indeed seems to be the case when I had both cameras in a controlled situation in a studio setup using the same lens, exposure settings, strobe power, and even manually set white balance of 5600k on both cameras. The 5DSR naturally produced a bit warmer and richer color palate (as in zero LightRoom adjustment on both cameras)
UPDATE 7/27 - Took the R to a small play my kids were in. 70-200 f2.8L IS II running in ISO 6400 the whole way through. Keeping at f2.8 I was getting anywhere from 160th to 320th in Aperture Priority mode with changing stage lighting. (Shooting RAW as always) Gotta say I'm still very pleased with the results, and even more so after a bit of NR added in Lightroom in the Luminance channel.
UPDATE 8/3 - DIFFRACTION LIMITS - Ok this is a bit more technical for us geeks but in general, all lenses become diffraction limited around f16, which has in recent history been correct with all our 20MP-ish cameras. Diffraction limits are correlated to pixel size and density though. So at 50MP, the same lens that was DL at f16 on a Canon 5D III is now DL between f11-f14 on a Canon 5DS. I have shot many frames at f11 on my 5DSR and they look amazing (using Canon 16-35L f4 IS). The diffraction effects will start creeping in beyond this, so effectively f11 is the smallest aperture you can stop down to before you begin to LOSE sharpness. a 5D III gets you to f16 because the pixels are much bigger than the 5DS. With the smaller pixels, more fine detail can be resolved so the DL hits sooner (bigger aperture). If you shoot a lot of Macro stuff I don't see much ever done smaller than f11-f14 anyway. So this should not be a problem. As for landscapers, f11 on a serious wide angle lens (assuming you're using good focus point technique) should get you close to infinity focus through the frame anyway. If you really need deeper focus, then consider focus stacking anyway. I don't think I've ever shot anything at f16 more than once or twice even on my 5D III.
1. Better out of the box dynamic range that you will notice,
2. Better exposure metering in bright daylight when us average guys shoot,
3. Has a fantastic electronic level so I can finally get my shots straight,
4. Resolution finally exceeds your ability to shoot handheld so this ends the megapixel war (so everyone stop talking about it),
5. There is a usable gain in resolution over the 5D Mark III if you use a tripod and mirror lock up (so this is rare),
6. They put a USB 3 on the side with a cable protector (finally) so you can safely shoot tethered, this was a problem with the Mark III with the slower USB port,
7. It has usable mirror lock up delays that do help get better pictures,
8. The silent shutter is much nicer (pleasing to the ear) and make you bother people less at performances or weddings...
Bottom line, if I had a choice between the 5D Mark III and the 5DS even just for walk around shooting in any light, I would pick the 5DS hands down.
- ISO6400 Limit - I never really had a need to go past 6400 on any body given the grain that is added. So I don't see this as a limiting factor. The noise added on the A7RII is also quite appreciable and oddly, prefer Canon's signature. I have not used the A7S or the new A7SII so the grain may be less noticeable on those bodies given the larger pixels.
- Mirror Lock-Up Delay - On the Canon 5D3 for years, I used the 10-second delay with Live-View which basically did the same thing and creates an electronic first-curtain. Marketing at its best here.
- Pixel Noise - Both bodies have visible noise when images are magnified (pixel peep); with the Canon there is a bit more however, at base ISO settings. Given the 5DSR has more resolution, you can sacrifice some of that by dialing in a bit more noise reduction bringing the noise level to about the same. At higher ISO settings, the noise looks to be similar between the two. However, if your aim is going for exposures longer than 2 minutes, I can't recommend either body and would recommend a 20-something MP body. It seems those little pixels get hot quickly on both the Sony and Canon and leave hot-pixel artifacts.
- Dynamic Range - Yep, the A7RII has more DR, it's well documented, at native ISO settings. What's not well talked about is the DR is about the same from ISO1600 onward. Further, if one exposes correctly, you shouldn't need to pull 5-stops of shadows up, which cause photos to look a bit baked. This topic is a bit overblown (sorry couldn't resist that pun). I must admit however, the raw files coming out of the Canon have a higher contrast than the Sony, I wonder if the processing is artificially destroying some DR bandwidth and clipping the shadows and highlights - unfortunately, I leave that answer to those who more technical than myself.
- Lenses - There are some pretty good lenses native to the Sony mount and Sony's stable is getting bigger and better all the time, largely with the help of Zeiss (love those Loxias). But if you need scalpel-sharp images availing a high megapixel sensor, the EF mount is really the only place you will find what you're looking for right now for anything on the Canon or the Sony. Some lenses on the EF mount simply don't have a Sony-mount peer - ironically with the help of Zeiss (think Otus & APO135). The new 35mm f/1.4L II and 300mm f/2.8L IS II also really make the 5DSR sing. Mounting any of these EF lenses to the Sony negates any idea of a small inconspicuous package.
- Focus - Focusing Canon lenses on the A7RII is better now than on previous models, but still not quite as good as on a Canon body. The longer telephoto and super-telephoto's are not so good on the Sony.
- Build - This one is pretty clear to me, I have taken a 5D3 out in rainstorms and torrential blizzards where I've had to chip away at the ice that collected on the body - no problems over the years of abuse with operations and functions. I assume the 5DSR is at least as rugged. I just don't have that same confidence in subjecting the Sony to the same abuse - time might tell if I get brave and I'll report back.
- Ergonomics - I really wish I could re-assign the magnification button to somewhere on the right hand so I can hit LiveView and magnification without having to bring my left hand back behind the camera (it's usually holding a heavy lens. Otherwise, those coming from a Canon 5D# or 1D# body should come up right to speed with the 5DSR. P.S., the Sony isn't as bad as everyone says it is once you get accustomed to where things are.
- Moire - Not normally a problem, but there have been a few instances of shooting buildings where I get patterns on the shades in the windows and of the air-duct exhaust fins on buildings, but usually only see them when zoomed in. Very little problem here.
Generally, between the two models and all the hype/bash that was floating around, the Canon 5DSR compared more favorably (maybe my expectations were low) and the Sony A7RII compared less favorably (maybe my expectations were high) - so it seems reality is somewhere between all the hubbub.
My only advice is to know what you'll be using the camera for, don't get upset that the screwdriver you bought is not able to pound in the nails like a hammer. If you need insane resolution where you'll be blowing up prints that people will actually be viewing up close to (versus a billboard), Canon has produced a wonderful tool for architecture, landscapes, macro, portraiture, etc., and this might be your ticket. But the 5DSR is remarkably unforgiving to a lazy or casual photographer that relies on post-production to get things right.
If undecided, go out and rent them to find out which fits you best. Both are remarkable tools and should fully satisfy your needs, if those needs fall within each camera's respective capability. Peace & Happy Shooting!
