Panasonic G3 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine FHD processor. On the other hand, Panasonic G1 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .
Below you can see the G3 and G1 sensor size comparison.
Panasonic G3 and Panasonic G1 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 G1 has 31% larger pixel area (18.74µm2 vs 14.21µm2) compared to Panasonic G3, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Panasonic G3 and Panasonic G1 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, G3 has scored 56, 3 points higher than G1.
