Olympus 6020 has a
13.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features TruePic III processor. On the other hand, Ricoh WG-8 has a
20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Ricoh WG-8's sensor provides 7MP more than Olympus 6020's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the 6020 and WG-8 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus 6020 and Ricoh WG-8 Cameras
Olympus 6020 and Ricoh WG-8 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 6020
or the
Ricoh WG-8 ,
including hyperfocal distance.
