Image quality

The Canon EOS 5DS R gives very good results at sensitivities up to ISO 3200 at least.

The Canon EOS 5DS R’s 50.6MP sensor represents a real step-change for Canon users, compared to the 22.3MP offered by the 5D Mark III. The increase in detail is striking, and improved in-camera sharpening means that it can all be delivered in the camera’s JPEG output. This does come at the cost of high ISO capability, but even at the extended setting of ISO 12,800 images are perfectly useable. This suggests that the limited ISO range available is a rather conservative decision on Canon’s part, presumably to help differentiate the 5DS twins from the 5D Mark III.

Colour rendition is typical Canon, with an attractive palette in the default JPEG mode that’s saturated without being unrealistic, aided by reliable auto white balance. Dynamic range, while not class-leading, is still very respectable, with plenty of detail recoverable in the shadow regions of low ISO images. Overall the 5DS R gives exceptional images.

Resolution

As we’d expect from a 50MP sensor with no optical low-pass filter, the 5DS R gives remarkable results in our resolution tests. At ISO 50 it resolves very close to its theoretical maximum of 5600l/ph, although with some aliasing and false colour around this point, and plenty of false detail at higher frequencies. This impressive resolution drops only slightly as the sensitivity is increased, with 5200l/ph still attained at ISO 800, and 4800l/ph at the top setting of ISO 12800.

Below are 100% crops from our resolution chart, shot using the Canon EF 100mm f/2.8 Macro USM at f/4. Note that because of the 5DS R’s high resolution we’ve shot from double the distance as usual, and the numbers on the graph need to be multiplied by 200 to get the resolution in lines per picture height.

Dynamic Range

The EOS 5DS R gives very good results in our Applied Imaging tests, if not entirely class-leading. At ISO 50 it returns 12.4 stops of dynamic range, indicating that there should be plenty of additional shadow detail retrievable from raw files. Initially this drops only slightly as the sensitivity is increased, but beyond ISO 400 it falls off more rapidly. But even at the highest standard setting of ISO 6,400, it still produces a very respectable 8.1EV of dynamic range, which should give perfectly usable images.

  • Michal Rosa

    Honesty is good.

  • Stefan Stroebele

    Thanks for the good review. the 5DS offeres also 2 modes of reduced resolution. What would the dynamic range be in the reduced resolution mode? If Canon engineers did a good job it should go up by an entire stop. But on my current model (60D) it does not. did anyone already look at this aspect?

  • I’m trolling and clueless both

  • Michal Rosa

    Are you paid for trolling or just clueless?

  • Prob is that you can’t trust Sony too much, what they are saying does not always translate in what is actually true. An acquaintance of mine told me with no doubts whatsoever that Nikon and Canon are getting ready to fight the fight at open arms with Sony and we will be thankful to Sony for the “gifts” as he put it, they we are going to get thanks to them. We will see, but I’m tired of waiting I need to shoot high ISO at fast shutter speeds and so far neither 5D3 or 1DX are giving me that. I cannot go over 16000 ISO which is already pretty noisy. I read that 5DM4 will have a substantial improvement in high ISO, that would make me get one right away and forget Sony for a bit:)

  • John Tharp

    I’m actually thinking the same thing, at some point. I’m shooting a 6D now; the 5Ds is more of what I don’t need and less of what I do (not that it wouldn’t be a suitable replacement, just not really an upgrade).

    It really depends on what happens with the 5D IV. If Canon can make gains in terms of DR at lower ISOs while also making general improvements, a la the newer features in the 7D II and 5Ds, while putting in a bit more 1D X DNA, I could easily be won over for the better handling and better system and support.

  • John Tharp

    I’ve seen that; of course, the issue is that we’ve only seen a few samples with a few lenses in a few situations.

    Are we talking Rebel-level tracking (still better than most mirrorless) at a dog park or are we talking 1D X-level tracking at a sporting event, etc.?

    That’s the question that will hopefully be answered soon!

  • EXACTLY! I’m stuck with Canon sadly, if that AF will actually work fast with Canon lenses I’m in! I’ll get a7r II and a7s II whenever that will be

  • Sigma

    Actually, Sony has been showcasing the a7rII’s ability to AF and track quickly and reliably with Canon adapted lenses. There are a few bloggers/reviewers who have had a chance to test it out, and they reporting that this is indeed the case. There are a few videos starting to trickle down.

    So 42mp A7rII with backlit sensor (greater sensitivity vs the 5DSR which caps out at ISO6400), greater dynamic range, in body image stabilization, native 4K, 399 AF points, and the ability to AF Canon lenses quickly. The only thing Canon has going for it is a modest MP advantage

  • John Tharp

    That A7r II that can be mounted behind the best telephoto lenses made with fast and accurate AF while tracking moving subjects in less than ideal conditions?

    The A7’s may have better shadow-levity at 100-400 ISO, and that’s great and all, but they’re still limited by Sony’s system. A better comparison will be the Nikon D800-series body that is eventually released with that same 42MP sensor.

  • Arkarch

    I got the 5DS a few days ago and love it. Works, feels and uses the same accessories as my old friend the 5D3. The same great Canon User Interface with an optical view finder you can compose and filter with. I might quibble a bit with the 5DS/5DsR choice; the nature impulse is the 5DsR, but I actually am in the 5DS camp for a more pleasing and smooth image – Adding blur to a sampled image is not the same as subtle anti-alias using the actual image. But this is a subjective choice and either choice based on your needs and shooting/post styles will work well. DR does seem to be better. Color is wonderful. Thank-you for the review!

  • lol the camera barely came out and it’s already killed buy the sony A7r II another boring camera from Canon reusing older sensors….whet are they gonna wake up and innovate?!?
