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, Fujifilm JX500 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the V-Lux 20 and JX500 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 20 and Fujifilm JX500 Cameras
Leica V-Lux 20 and Fujifilm JX500 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 20
or the
Fujifilm JX500 ,
including hyperfocal distance.
