Leica M10-P has a
24.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Maestro II processor. On the other hand, Nikon D780 has a
25.0MP Full frame (35.9 x 23.9 mm ) sized BSI-CMOS sensor and features Expeed 6 processor.
Below you can see the M10-P and D780 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M10-P and Nikon D780 Cameras
Leica M10-P and Nikon D780 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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-P
or the
Nikon D780 ,
including hyperfocal distance.
