Leica M10 Monochrom has a
41.0MP Full frame (36 x 24 mm ) sized Monochrome CMOS sensor and features Maestro II processor. On the other hand, Leica M-Monochrom has a
18.0MP Full frame (36 x 24 mm ) sized Monochrome CCD sensor .
Leica M10 Monochrom's sensor provides 23MP more than Leica M-Monochrom'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.
Below you can see the M10 Monochrom and M-Monochrom sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M10 Monochrom and Leica M-Monochrom Cameras
Leica M10 Monochrom and Leica M-Monochrom 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 Leica M-Monochrom has 32% larger pixel area (47.73µm 2 vs 36.01µm 2 ) compared to Leica M10 Monochrom, 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 M10 Monochrom
or the
Leica M-Monochrom ,
including hyperfocal distance.
