Samsung NX mini has a
20.5MP 1' (13.2 x 8.8 mm ) sized BSI-CMOS sensor . On the other hand, Olympus E-M1X has a
20.0MP Four Thirds (17.4 x 13 mm ) sized CMOS sensor and features Dual TruePic VIII processor.
Below you can see the NX mini and E-M1X sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX mini and Olympus E-M1X Cameras
As seen above, Olympus E-M1X has a 1.9x Larger sensor area than Samsung NX mini. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Samsung NX mini
or the
Olympus E-M1X ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1' versus Four Thirds),
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.
