Leica V-Lux 20 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Leica V-Lux 40 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor .
Below you can see the V-Lux 20 and V-Lux 40 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 20 and Leica V-Lux 40 Cameras
Leica V-Lux 20 and Leica V-Lux 40 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 V-Lux 20 has 16% larger pixel area compared to Leica V-Lux 40, 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 V-Lux 20
or the
Leica V-Lux 40 ,
including hyperfocal distance.
