Both Panasonic GF5 and Panasonic G1 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 GF5 and G1 sensor size comparison.
Panasonic GF5 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.
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 GF5 and Panasonic G1 sensors have been tested by DxO and the results show that G1 has a better overall score of 53, 3 points higher compared to GF5's score of 50.
