Blackmagic PYXIS 12K has a
98.8MP Full frame (35.6 x 23.3 mm ) sized CMOS sensor . 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 PYXIS 12K and URSA Cine 12K LF sensor size comparison.
Sensor Size and Resolution Comparison image of Blackmagic PYXIS 12K and Blackmagic URSA 12K LF Cameras
Blackmagic PYXIS 12K and Blackmagic URSA 12K LF have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 PYXIS 12K
or the
Blackmagic URSA 12K LF ,
including hyperfocal distance.
