Well after months of waiting on pre-order, it finally arrived. Here's the high points thus far:
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.

Amazing camera. 50MP does the job.
Reviewed in the United States on September 17, 2016
The Canon 5DS R has become my go-to camera. I was running the 5D Mark III and was thinking about going to the Mark IV but after about 6 months of running with the 5DS R, I have to say that I'm not going to give it up any time soon unless the 5DS R Mark II comes out.
Sure, the stats on it aren't great. 5FPS. Buffer fills up quickly. File sizes can be unmanageable if your computer isn't up to snuff. Gotta have good glass in order to take full advantage of the 50MP sensor.
But it does take some great photos where the depth of colour is incredible and the flexibility in post is almost limitless. The details that this sensor renders is just amazing.
My style of shooting is generally with my boy and his friends - always running around doing something either indoors or outdoors. My favourite go-to lens for this camera is the Canon 24-70 f/2.8L II and it does a superb job in giving me the photos I want. So I'm usually running and gunning trying to capture the moment and then I'll download the RAW files and crop in LR. After getting used to the workflow, I have really come to appreciate the fact that I am able to run and gun and then figure out the composition afterwards. While some other photographers would like to frame the subject, compose the shot and then shoot, that's just not possible with a bunch of 3-4 year old boys so usually the style is take shots on the run.
The ability to crop, the colours and the sheer detail from the sensor is what really sets this camera apart.
The only downside to this is that if you're not running a fast CF card with sufficient storage, you may run into buffer and/or not enough shots scenario. I personally run a Sandisk Extreme Pro 64GB 160 MB/s card and that will give me 720 shots with full RAW - which, to me, is enough for a day of shooting. There are times when the autofocus isn't as great as say the 1DX Mark II or the new 5D Mark IV but my miss rate is about the same as when I was using the 5D Mark III as my primary rig.
People have said that the 6400 max ISO isn't enough - personally, if I'm approaching 3200, I'll stop down the shutter speed (as I usually shoot wide open on a minimum f/2.8). I've pushed the camera up to 6400 and while the files are usable, I've had to apply some measure of noise reduction in LR while in post.
There have been reviewers that have said that good technique is necessary for this camera - while that is true, lens selection also plays a part. If you're not using a minimum of the the 2x focal length rule, then you will get some soft images if your technique isn't great. I've handheld in darker conditions without any issues because of my lens selection.
Moire has not been an issue. 20,000 shutter clicks so far and I haven't seen anything.
Personally, while I have yet to shoot any sports with this, I really believe it is able to handle it (if you're OK with 5FPS) because of some of the incredible shots I get of my boy and his friends when they're playing/running - while they don't run as fast as athletes do, there are comparables in terms of trying to capture action. Obviously, if you're a serious sports shooter, then the 1DX Mark II is the way to go.
Ergonomics is classic Canon 5 series. Can't beat it - if you've shot the 5 series for any length of time and you pick this camera up, you'll feel right at home. The build is also incredible - almost indestructible. My boy dropped my camera on a hardwood floor and the only thing that broke (and required a $70 repair) was the battery cover - had to be drilled out because we couldn't pop the battery cover off.
In all, this is my favourite camera so far and I've run quite a few Canon and Sony cameras. If you're wondering whether this will handle low light with faster action, then the answer is yes so long as you put fast glass on it.
