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, Canon SX610 HS has a
20.0MP 1/2.3' (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 4+ processor.
Below you can see the E-M10 III and SX610 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-M10 III and Canon SX610 HS Cameras
As seen above, Olympus E-M10 III has a 8.1x Larger sensor area than Canon SX610 HS. 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 E-M10 III
or the
Canon SX610 HS ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds versus 1/2.3' ),
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.
