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, Olympus TG-820 iHS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features TruePic VI processor.
Below you can see the TG-810 and TG-820 iHS sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus TG-810 and Olympus TG-820 iHS Cameras
Olympus TG-810 and Olympus TG-820 iHS 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
Olympus TG-820 iHS ,
including hyperfocal distance.
