Nikon A100 has a
20.0MP 1/2.3' (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Nikon AW100 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the A100 and AW100 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon A100 and Nikon AW100 Cameras
Nikon A100 and Nikon AW100 have the same sensor sizes so they will provide same level of control over the depth of field when used with 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
Nikon A100
or the
Nikon AW100 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3' 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.
