Kodak Z1485 IS has a
14.0MP 1/1.72-inch (7.4 x 5.55 mm ) sized CCD sensor . On the other hand, Sony TX20 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor.
Below you can see the Z1485 IS and TX20 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak Z1485 IS and Sony TX20 Cameras
As seen above, Kodak Z1485 IS has a 1.5x Larger sensor area than Sony TX20. 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 Z1485 IS
or the
Sony TX20 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.72-inch versus 1/2.3-inch),
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.
