IMAGE QUALITY & PERFORMANCE - CANON EOS 5DS R
We must admit that coming into this shootout, we expected the EOS 5DS R to be the most sluggish camera of the lot, given the sheer amount of data it would have to move per shot. To our pleasant surprise, that wasn’t the case at all. The rated continuous shooting rate for the 5DS R is five frames, which is actually quite an impressive achievement. Despite having to move about 50 megabytes with every shot, the camera was fairly responsive, and the buffer for continuous shooting certainly seemed adequate for most types of photography. Canon has listed its shooting performance as 31 frames on JPEG Large/Fine, and 12 Frames on RAW, which are certainly serviceable numbers. Autofocus was also generally fast and accurate even in low-light situations, and the amount of detail you got in every shot was certainly the most we’ve seen from any 35mm format DSLR.
ISO 6,400 is the highest we’d go with this camera after sharpening.
The texture of the underlying wall is clearly visible in the image captured by the 5DS R.
