My last point would be that the continued claims that you cannot hand hold the 5DS R and get sharp pictures is false. Is it more demanding than a 5D MKIII?
The claim is complete BS and you have to wonder why Dustin does not make it clear: sharpness is 100% the same handheld as with a 5DIII - 100%. However, if you use a stable setup such as a good tripod it can produce far sharper pictures than you can ever make with a 5DIII. So much for that downside.
Worse is that Dustin is plain and simply wrong on the noise of the 5DS/R and it does him very little credit to write that the 5DS/R has a disadvantage here compared to the 5DIII.
Noise is better on the 5DS/R than the 5DIII. And you do not have to do anything - zero - to getter better results. All this nonsense about "downsampling" has completely confused people.
Fact is this: if you are looking at the same picture from a 5DIII and a 5DS/R on a screen or in print the 5DS/R will always have at least as good - and very often - better noise than the picture taken with a 5DIII. And you do not have to do anything at all with the 5DS/R picture to achieve this. Its only if you view a larger 5DS/R picture than the 5DIII picture you notice anything. But hey! - that's of course a totally unfair way of comparing the noise in two pictures of the same subject.
When it comes to the iso-settings of the 5DS/R I'd expect someone who claims to be a reviewer to get it right: you can shoot the 5DS/R @ iso 12.800 and adjust in post to iso 100.000+ or 350.000+ or 1.000.000+ iso with the same results as you get with a 5DIII. Actually better, because even if noise will be very much the same banding is better (less) on the 5DS/R at these extremes.
Fact is, that for a photographer (not video) the one and only downside of shooting with a 5DS/R against a 5DII is 5 vs 6 fps - in my view a non-essential difference: they are both too slow if speed is your thing.
Everything else is better on the image side, were it really counts, color, DR, noise, WB, anti-flicker etc. And of course the 50MB that allows you to do so much more with your pictures.
On the non-image side seems odd to me that Dustin does not mention that the 5DS/R has much better AF than the 5DIII - including being able to autofocus down to ev-3.
5DS/R is not a perfect camera. No camera is or will ever be. But in the very direct comparision Dustin chooses with the 5DIII I cannot imagine even one single situation were the 5DS/R would not be the better choice than a 5DIII. But if anyone can imagine such a situation it would be interesting.
Building his premise on this assumption I can only conclude that the reviewer went into the testing and review with a firm pre-determined conclusion in his mind.
