Olympus E-M10 III has a
16.0MP Four Thirds (17.4 x 13 mm ) sized CMOS sensor and features TruePic VIII processor. On the other hand, Olympus E-620 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic III+ processor.
Below you can see the E-M10 III and E-620 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-M10 III and Olympus E-620 Cameras
Olympus E-M10 III and Olympus E-620 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 E-M10 III
or the
Olympus E-620 ,
including hyperfocal distance.
