Fujifilm GFX 50S II has a
51.0MP Medium format (44 x 33 mm ) sized CMOS sensor and features X-Processor 4 processor. On the other hand, Sony A1 II has a
50.0MP Full frame (35.9 x 24 mm ) sized Stacked CMOS sensor and features Dual Bionz XR processor.
Below you can see the GFX 50S II and A1 Mark II sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm GFX 50S II and Sony A1 II Cameras
As seen above, Fujifilm GFX 50S II 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
Fujifilm GFX 50S II
or the
Sony A1 II ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Medium format versus Full frame),
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.
