Nikon Z6 has a
24.0MP Full frame (35.9 x 23.9 mm ) sized BSI-CMOS sensor and features Expeed 6 processor. On the other hand, Sony QX100 has a
20.0MP 1-inch (13.2 x 8.8 mm ) sized BSI-CMOS sensor .
Below you can see the Z6 and QX100 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon Z6 and Sony QX100 Cameras
As seen above, Nikon Z6 has a 7.4x Larger sensor area than Sony QX100. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 Z6
or the
Sony QX100 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus 1-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
