Below you can see the Komodo-X 6K and Cinema Camera 6K Pro sensor size comparison.
Sensor Size and Resolution Comparison image of RED Komodo-X 6K and Blackmagic 6K Pro Cameras
As seen above, RED Komodo-X 6K has a 1.3x Larger sensor area than Blackmagic 6K Pro. 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
RED Komodo-X 6K
or the
Blackmagic 6K Pro ,
including hyperfocal distance.
