Sony FX9 has a
19.0MP Full frame (35.7 x 18.8 mm ) sized CMOS sensor . On the other hand, RED Komodo-X 6K Z has a
19.9MP Super 35 (27.03 x 14.26 mm ) sized CMOS sensor .
Below you can see the FX9 and Komodo-X 6K Z sensor size comparison.
Sensor Size and Resolution Comparison image of Sony FX9 and RED Komodo-X 6K Z Cameras
As seen above, Sony FX9 has a 1.7x Larger sensor area than RED Komodo-X 6K Z. 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
Sony FX9
or the
RED Komodo-X 6K Z ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus Super 35),
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.
