Pentax WG-2 GPS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Olympus SP-600 UZ has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features TruePic III processor.
Below you can see the WG-2 GPS and SP-600 UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax WG-2 GPS and Olympus SP-600 UZ Cameras
Pentax WG-2 GPS and Olympus SP-600 UZ 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
Pentax WG-2 GPS
or the
Olympus SP-600 UZ ,
including hyperfocal distance.
