Both Nikon Z fc and Nikon Z30 have APS-C sized 21.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another similarity between these two cameras is that both Nikon Z30 and Nikon Z fc sensors lack anti-alias (Low-Pass) filters. 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 Z fc and Z30 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon Z fc and Nikon Z30 Cameras
Nikon Z fc and Nikon Z30 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
Nikon Z fc
or the
Nikon Z30 ,
including hyperfocal distance.
