Olympus FE-5010 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Pentax WS80 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Prime processor.
Below you can see the FE-5010 and WS80 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus FE-5010 and Pentax WS80 Cameras
Olympus FE-5010 and Pentax WS80 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
Olympus FE-5010
or the
Pentax WS80 ,
including hyperfocal distance.
