Canon R6 has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Leica M Edition 60 has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor .
Below you can see the R6 and M Edition 60 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R6 and Leica M Edition 60 Cameras
Canon R6 and Leica M Edition 60 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 R6 has 17% larger pixel area compared to Leica M Edition 60, 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
Canon R6
or the
Leica M Edition 60 ,
including hyperfocal distance.
