Nikon Z5 has a
24.0MP Full frame (35.9 x 23.9 mm ) sized CMOS sensor and features Expeed 6 processor. On the other hand, Canon RP has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Digic 8 processor.
Below you can see the Z5 and EOS RP sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon Z5 and Canon RP Cameras
Nikon Z5 and Canon RP 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 Z5
or the
Canon RP ,
including hyperfocal distance.
