Canon S120 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor and features Digic 6 processor. 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 S120 and LX7 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon S120 and Panasonic LX7 Cameras
Canon S120 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 Canon S120, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Canon S120 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, S120 has scored 56, 6 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
Canon S120
or the
Panasonic LX7 ,
including hyperfocal distance.
