Nikon P340 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor . On the other hand, Leica D-Lux 6 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Venus Engine processor.
Below you can see the P340 and D-Lux 6 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P340 and Leica D-Lux 6 Cameras
Nikon P340 and Leica D-Lux 6 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 D-Lux 6 has 20% larger pixel area (4.16µm 2 vs 3.46µm 2 ) compared to Nikon P340, 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
Nikon P340
or the
Leica D-Lux 6 ,
including hyperfocal distance.
