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-M5 III has a
20.0MP Four Thirds (17.4 x 13 mm ) sized MOS sensor and features TruePic VIII processor.
Below you can see the E-M10 III and E-M5 Mark III sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-M10 III and Olympus E-M5 III Cameras
Olympus E-M10 III and Olympus E-M5 III 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 E-M10 III has 26% larger pixel area compared to Olympus E-M5 III, 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 E-M10 III
or the
Olympus E-M5 III ,
including hyperfocal distance.
