Fujifilm GFX Eterna 55 has a
102.0MP Medium format (44 x 33 mm ) sized BSI-CMOS sensor and features X-Processor 5 processor. On the other hand, Blackmagic URSA 12K LF has a
98.0MP Full frame (35.64mm x 23.32mm ) sized CMOS sensor .
Below you can see the GFX Eterna 55 and URSA Cine 12K LF sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm GFX Eterna 55 and Blackmagic URSA 12K LF Cameras
As seen above, Fujifilm GFX Eterna 55 has a 1.7x Larger sensor area than Blackmagic URSA 12K LF. 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 Eterna 55
or the
Blackmagic URSA 12K LF ,
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.
