Canon A1100 IS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4 processor. On the other hand, Leica X Vario has a
16.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor .
Below you can see the A1100 IS and X Vario sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A1100 IS and Leica X Vario Cameras
As seen above, Leica X Vario has a 13.3x Larger sensor area than Canon A1100 IS. 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
Canon A1100 IS
or the
Leica X Vario ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch 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.
