Nikon P340 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor . On the other hand, Panasonic LX7 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 LX7 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P340 and Panasonic LX7 Cameras
Nikon P340 and Panasonic LX7 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 Panasonic LX7 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.
DxOMark Sensor Scores
Both Nikon P340 and Panasonic LX7 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, P340 has scored 54, 4 points higher than LX7.

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
Panasonic LX7 ,
including hyperfocal distance.
