Sony A1 II has a
50.0MP Full frame (35.9 x 24 mm ) sized Stacked CMOS sensor and features Dual Bionz XR processor. On the other hand, Hasselblad X1D has a
51.0MP Medium format (44 x 33 mm ) sized CMOS sensor .
Below you can see the A1 Mark II and X1D sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A1 II and Hasselblad X1D Cameras
As seen above, Hasselblad X1D has a 1.7x Larger sensor area than Sony A1 II. 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
Sony A1 II
or the
Hasselblad X1D ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus Medium format),
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.
