Canon 1D MIII has a
10.0MP APS-H (28.7 x 18.7 mm ) sized CMOS sensor . On the other hand, Leica V-Lux 30 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor and features Venus Engine FHD processor.
Below you can see the 1D MIII and V-Lux 30 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1D MIII and Leica V-Lux 30 Cameras
As seen above, Canon 1D MIII has a 19.4x Larger sensor area than Leica V-Lux 30. 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 1D MIII
or the
Leica V-Lux 30 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-H 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.
