Leica M Edition 60 has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor . On the other hand, Canon R6 has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor.
Below you can see the M Edition 60 and R6 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M Edition 60 and Canon R6 Cameras
Leica M Edition 60 and Canon R6 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 (43.00µm 2 vs 36.50µm 2 ) compared to Leica M Edition 60, it has larger pixel area to collect light hence potential to 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 M Edition 60
or the
Canon R6 ,
including hyperfocal distance.
