FujiFilm S4000 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Ricoh GXR A16 24-85mm has a
16.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features Smooth Imaging Engine IV processor.
Below you can see the S4000 and GXR A16 24-85mm F3.5-5.5 sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm S4000 and Ricoh GXR A16 24-85mm Cameras
As seen above, Ricoh GXR A16 24-85mm has a 13.2x Larger sensor area than FujiFilm S4000. 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
FujiFilm S4000
or the
Ricoh GXR A16 24-85mm ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus APS-C),
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.
