Blackmagic URSA 12K LF has a
98.0MP Full frame (35.64mm x 23.32mm ) sized CMOS sensor . On the other hand, Hasselblad X2D has a
100.0MP Medium format (44 x 33 mm ) sized CMOS sensor .
Below you can see the URSA Cine 12K LF and X2D 100c sensor size comparison.
Sensor Size and Resolution Comparison image of Blackmagic URSA 12K LF and Hasselblad X2D Cameras
As seen above, Hasselblad X2D 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
Blackmagic URSA 12K LF
or the
Hasselblad X2D ,
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.
