Sensor Size and Resolution Comparison image of Nikon D780 and Nikon Z6 II Cameras
Nikon D780 and Nikon Z6 II 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 D780
or the
Nikon Z6 II ,
including hyperfocal distance.
