Leica M10-R has a
41.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Maestro II processor. On the other hand, Canon R5 II has a
45.0MP Full frame (36 x 24 mm ) sized Stacked CMOS sensor and features Digic X processor.
Below you can see the M10-R and R5 Mark II sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M10-R and Canon R5 II Cameras
Leica M10-R and Canon R5 II 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 Leica M10-R has 86% larger pixel area compared to Canon R5 II, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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
Leica M10-R
or the
Canon R5 II ,
including hyperfocal distance.
