19.9MP Super 35 (27.03 x 14.26 mm ) sized CMOS sensor .
Below you can see the Cinema Camera 6K G2 and Komodo 6K sensor size comparison.
Sensor Size and Resolution Comparison image of Blackmagic 6K G2 and RED Komodo 6K Cameras
As seen above, RED Komodo 6K has a 1.3x Larger sensor area than Blackmagic 6K G2. 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 6K G2
or the
RED Komodo 6K ,
including hyperfocal distance.
