Olympus TG-810 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor. On the other hand, OM System TG-7 has a
12.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features TruePic VIII processor.
Below you can see the TG-810 and TG-7 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus TG-810 and OM System TG-7 Cameras
Olympus TG-810 and OM System TG-7 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.
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-810
or the
OM System TG-7 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus ),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
