Leica M EV1 has a
60.0MP Full frame (36 x 24 mm ) sized BSI-CMOS sensor and features Maestro III processor. On the other hand, Pixii Max has a
24.5MP Full frame (36 x 24 mm ) sized CMOS sensor .
Leica M EV1's sensor provides 35.5MP more than Pixii Max'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 Pixii Max'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 M EV1 and Max (A3410) sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M EV1 and Pixii Max Cameras
Leica M EV1 and Pixii Max 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 Pixii Max has 151% larger pixel area (36.01µm 2 vs 14.33µm 2 ) compared to Leica M EV1, 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 M EV1
or the
Pixii Max ,
including hyperfocal distance.
