Canon 5DS R has a
51.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Dual DIGIC 6 processor. On the other hand, Canon 5D has a
13.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic II processor.
Canon 5DS R's sensor provides 38MP more than Canon 5D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Another difference between these two cameras is that Canon 5DS R's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the 5DS R and 5D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 5DS R and Canon 5D Cameras
Canon 5DS R and Canon 5D have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon 5D has 295% larger pixel area (67.92µm 2 vs 17.17µm 2 ) compared to Canon 5DS R, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Canon 5DS R and Canon 5D sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, 5DS R has scored 86, 15 points higher than 5D.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon 5DS R
or the
Canon 5D ,
including hyperfocal distance.
