Canon 1D X II has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Dual DIGIC 6+ processor. On the other hand, Leica M Typ 262 has a
24.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Maestro processor.
Below you can see the 1D X MII and M Typ 262 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1D X II and Leica M Typ 262 Cameras
Canon 1D X II and Leica M Typ 262 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
Canon 1D X II
or the
Leica M Typ 262 ,
including hyperfocal distance.
