Panasonic FH25 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine VI processor. On the other hand, Leica V-Lux 4 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor .
Below you can see the FH25 and V-Lux 4 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH25 and Leica V-Lux 4 Cameras
Panasonic FH25 and Leica V-Lux 4 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Leica V-Lux 4 has 32% larger pixel area (2.31µm 2 vs 1.74µm 2 ) compared to Panasonic FH25, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
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
Panasonic FH25
or the
Leica V-Lux 4 ,
including hyperfocal distance.
