Both Panasonic GH2 and Panasonic G5 have Four Thirds sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the GH2 and G5 sensor size comparison.
Panasonic GH2 and Panasonic G5 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Panasonic GH2 and Panasonic G5 sensors have been tested by DxO and the results show that G5 has a better overall score of 61, 1 points higher compared to GH2's score of 60.
