Both Panasonic G1 and Panasonic GF1 have Four Thirds sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the G1 and GF1 sensor size comparison.
Panasonic G1 and Panasonic GF1 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 G1 and Panasonic GF1 sensors have been tested by DxO and the results show that GF1 has a better overall score of 54, 1 points higher compared to G1's score of 53.
