Olympus TG-6 has a
12.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features TruePic VIII processor. On the other hand, Ricoh WG-90 has a
16.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the TG-6 and WG-90 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus TG-6 and Ricoh WG-90 Cameras
Olympus TG-6 and Ricoh WG-90 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. On the other hand, since Olympus TG-6 has 32% larger pixel area compared to Ricoh WG-90, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 TG-6
or the
Ricoh WG-90 ,
including hyperfocal distance.
