Sensor Size and Resolution Comparison image of Nikon ZR and Blackmagic Cinema 6K Cameras
Nikon ZR and Blackmagic Cinema 6K 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 ZR
or the
Blackmagic Cinema 6K ,
including hyperfocal distance.
