Leica D-Lux 6 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Canon S110 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 D-Lux 6 and S110 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica D-Lux 6 and Canon S110 Cameras
Leica D-Lux 6 and Canon S110 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Leica D-Lux 6 has 20% larger pixel area compared to Canon S110, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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
Leica D-Lux 6
or the
Canon S110 ,
including hyperfocal distance.
