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, Sony W650 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features BIONZ processor.
Below you can see the V-Lux 30 and W650 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 30 and Sony W650 Cameras
Leica V-Lux 30 and Sony W650 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
Sony W650 ,
including hyperfocal distance.
