Panasonic GF2 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine FHD processor. On the other hand, Panasonic GH4 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine IX processor.
Below you can see the GF2 and GH4 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic GF2 and Panasonic GH4 Cameras
Panasonic GF2 and Panasonic GH4 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 GF2 has 32% larger pixel area compared to Panasonic GH4, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 GF2 and Panasonic GH4 sensors have been tested by DxO and the results show that GH4 has a better overall score of 74, 20 points higher compared to GF2's score of 54.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic GF2
or the
Panasonic GH4 ,
including hyperfocal distance.
