Canon EOS C80 has a
19.0MP Full frame (36 x 24 mm ) sized BSI Stacked CMOS sensor . On the other hand, Nikon Z7 II has a
46.0MP Full frame (35.9 x 23.9 mm ) sized BSI-CMOS sensor and features Dual Expeed 6 processor.
Nikon Z7 II's sensor provides 27MP more than Canon EOS C80'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 Nikon Z7 II'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 C80 and Z7 Mark II sensor size comparison.
Sensor Size and Resolution Comparison image of Canon EOS C80 and Nikon Z7 II Cameras
Canon EOS C80 and Nikon Z7 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 EOS C80
or the
Nikon Z7 II ,
including hyperfocal distance.
