Sony WX1 has a
10.0MP 1/2.4-inch (6.104 x 4.578 mm ) sized BSI-CMOS sensor and features Bionz processor. On the other hand, Canon G15 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Digic 5 processor.
Below you can see the WX1 and G15 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony WX1 and Canon G15 Cameras
As seen above, Canon G15 has a 1.5x Larger sensor area than Sony WX1. 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
Sony WX1
or the
Canon G15 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.4-inch versus 1/1.7-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.
