Olympus PEN-F has a
20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic VII processor. On the other hand, Ricoh GXR A16 24-85mm has a
16.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features Smooth Imaging Engine IV processor.
Below you can see the PEN-F and GXR A16 24-85mm F3.5-5.5 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus PEN-F and Ricoh GXR A16 24-85mm Cameras
As seen above, Ricoh GXR A16 24-85mm has a 1.6x Larger sensor area than Olympus PEN-F. 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
Olympus PEN-F
or the
Ricoh GXR A16 24-85mm ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds versus APS-C),
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.
