Pentax W80 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Nikon S01 has a
10.0MP 1/2.9-inch (4.96 x 3.72 mm ) sized CCD sensor and features Expeed C2 processor.
Below you can see the W80 and S01 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax W80 and Nikon S01 Cameras
As seen above, Pentax W80 has a 1.5x Larger sensor area than Nikon S01. 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
Pentax W80
or the
Nikon S01 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/2.9-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.
