Olympus E-M10 II has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic VII processor. On the other hand, Olympus E-M10 IV has a
20.0MP Four Thirds (17.4 x 13 mm ) sized CMOS sensor and features TruePic VIII processor.
Below you can see the E-M10 II and E-M10 IV sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-M10 II and Olympus E-M10 IV Cameras
Olympus E-M10 II and Olympus E-M10 IV 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 II
or the
Olympus E-M10 IV ,
including hyperfocal distance.
