Both Sony A350 and FujiFilm S2800HD have 14.0 MP resolution sensors but Sony A350's sensor is APS-C (23.6 x 15.8 mm ) and FujiFilm S2800HD's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since Sony A350's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to FujiFilm S2800HD.
Below you can see the A350 and S2800HD sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A350 and FujiFilm S2800HD Cameras
As seen above, Sony A350 has a 13.3x Larger sensor area than FujiFilm S2800HD. 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 A350
or the
FujiFilm S2800HD ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C 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.
