Nikon Z6 III has a
24.0MP Full frame (35.9 x 23.9 mm ) sized Partially-Stacked CMOS sensor and features Expeed 7 processor. On the other hand, Leica M11 Monochrom has a
60.0MP Full frame (36 x 24 mm ) sized Monochrome BSI-CMOS sensor and features Maestro III processor.
Leica M11 Monochrom's sensor provides 36MP more than Nikon Z6 III'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 Z6 Mark III and M11 Monochrom sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon Z6 III and Leica M11 Monochrom Cameras
Nikon Z6 III and Leica M11 Monochrom 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
Nikon Z6 III
or the
Leica M11 Monochrom ,
including hyperfocal distance.
