Canon RP has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Digic 8 processor. On the other hand, Nikon Z5 II has a
25.0MP Full frame (35.9 x 23.9 mm ) sized BSI-CMOS sensor and features Expeed 7 processor.
Below you can see the EOS RP and Z5 II sensor size comparison.
Sensor Size and Resolution Comparison image of Canon RP and Nikon Z5 II Cameras
Canon RP and Nikon Z5 II 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
Canon RP
or the
Nikon Z5 II ,
including hyperfocal distance.
