Panasonic G85 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Panasonic GH1 has a
12.0MP Four Thirds (18.89 x 14.48 mm ) sized CMOS sensor and features Venus Engine HD processor.
Another difference between these two cameras is that Panasonic G85's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the G85 and GH1 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic G85 and Panasonic GH1 Cameras
As seen above, Panasonic GH1 has a 1.2x Larger sensor area than Panasonic G85. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
Both Panasonic G85 and Panasonic GH1 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, G85 has scored 71, 7 points higher than GH1.

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 G85
or the
Panasonic GH1 ,
including hyperfocal distance.
