Panasonic AW-UB10 has a
10.2MP Four Thirds (19 x 13mm ) sized MOS sensor . On the other hand, Canon SX40 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the AW-UB10 and SX40 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic AW-UB10 and Canon SX40 HS Cameras
As seen above, Panasonic AW-UB10 has a 8.8x Larger sensor area than Canon SX40 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
Panasonic AW-UB10
or the
Canon SX40 HS ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds versus 1/2.3-inch),
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.
