I very much like the current version of the 5DSR. But it does have shortcomings that prevent it from being my main camera, as much as I dislike the softer output from the 5D4:
- More speed. The delay between shot and review can be several seconds, particularly after a burst Would also appreciate a bump in FPS, to around 7-8.
- Extended ISO range: although below modern FF standards, there are times I wish the camera natively reached 12,800 ISO instead of being capped at 6400.
Less important, a “nice to have”:
- Enhanced crop options: I like that on the new EOS R, you can select C-RAW mode and increase buffer capacity, as well as 1.6x cropped RAW shots at a smaller file size. I hope these can be extended to a 5DSR successor.
One last thing, to anyone on the fence about the 5DS series: if you are a details guy, and especially if you also own a 35 1.4, 85 1.4 or big white, I highly recommend this camera. Nothing else in the Canon system comes close, including the 5D4. There is no AA filter or aggressive NR algorithm (if you shoot RAW) to hold you back. Only your stability. I think I’ve only had the moire issue come up on two images (out of 1000+) and then, it was very slight and easily correctable. I will say that to get the most out of the sensor it is best to expose correctly or as close to it as possible.
