Canon’s EOS 5DS and 5DS R are the highest resolution full-frame DSLRs on the market right now, sharing the same 50.6-million-pixel sensor. The two are near identical, but in the 5DS R the effect of the optical low pass filter in front of the sensor has been ‘cancelled’. This results in higher resolution, but at the expense of image artefacts such as aliasing and moiré.

Canon EOS 5DS R Review – Features

Physically the cameras are based on the EOS 5D Mark III, with a near-identical body design. But to support the high-resolution sensor they gain a new shutter and mirror assembly that’s designed to minimise vibrations.

The in-camera sharpening algorithms have also been updated to help get the most detail out of the cameras’ image files.

The sensitivity range covers ISO 100-6400 as standard, and ISO 50-12800 extended, which looks a bit limited for a full-frame camera these days. Shutter speeds range from 30sec to 1/8000 sec, and continuous shooting maxes out at 5 frames per second. Essentially the 5DS R is optimised for studio work, and is slightly less of an all-rounder than the 5D Mark III.
