Panasonic GH2 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 G2 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine HD II processor.
Below you can see the GH2 and G2 sensor size comparison.
Panasonic GH2 and Panasonic G2 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 G2 has 32% larger pixel area (18.74µm2 vs 14.12µm2) compared to Panasonic GH2, 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 GH2 and Panasonic G2 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, GH2 has scored 60, 7 points higher than G2.
