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, Leica SL2 has a
47.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Maestro III processor.
Leica SL2's sensor provides 23MP more than Leica M10-P's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
One other difference between these two cameras that is worth mentioning is that Leica SL2's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the M10-P and SL2 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M10-P and Leica SL2 Cameras
Leica M10-P and Leica SL2 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
Leica SL2 ,
including hyperfocal distance.
