Pixii Max has a
24.5MP Full frame (36 x 24 mm ) sized CMOS sensor . On the other hand, Canon R1 has a
24.0MP Full frame (36 x 24 mm ) sized Stacked CMOS sensor and features Digic X processor.
Another difference between these two cameras is that Pixii Max's sensor lacks 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 Max (A3410) and R1 sensor size comparison.
Sensor Size and Resolution Comparison image of Pixii Max and Canon R1 Cameras
Pixii Max and Canon R1 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.
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
Pixii Max
or the
Canon R1 ,
including hyperfocal distance.
