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. On the other hand, Canon SX160 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 30 and SX160 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 30 and Canon SX160 IS Cameras
Leica V-Lux 30 and Canon SX160 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 30
or the
Canon SX160 IS ,
including hyperfocal distance.
