Panasonic FH3 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Pentax W90 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Prime processor.
Below you can see the FH3 and W90 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH3 and Pentax W90 Cameras
Panasonic FH3 and Pentax W90 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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
Panasonic FH3
or the
Pentax W90 ,
including hyperfocal distance.
