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, Sony H70 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 2 and H70 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 2 and Sony H70 Cameras
Leica V-Lux 2 and Sony H70 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
Sony H70 ,
including hyperfocal distance.
