Kodak Z5120 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Sony FX9 has a
19.0MP Full frame (35.7 x 18.8 mm ) sized CMOS sensor .
Below you can see the Z5120 and FX9 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak Z5120 and Sony FX9 Cameras
As seen above, Sony FX9 has a 23.9x Larger sensor area than Kodak Z5120. 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
Kodak Z5120
or the
Sony FX9 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus Full frame),
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.
