Leica V-Lux 2 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor . On the other hand, Canon ELPH 140 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4+ processor.
Below you can see the V-Lux 2 and ELPH 140 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 2 and Canon ELPH 140 IS Cameras
Leica V-Lux 2 and Canon ELPH 140 IS have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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
Leica V-Lux 2
or the
Canon ELPH 140 IS ,
including hyperfocal distance.
