Both Panasonic GF5 and Panasonic GF3 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 GF3 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic GF5 and Panasonic GF3 Cameras
Panasonic GF5 and Panasonic GF3 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
At Camera Decision, we also look at Dxo Mark sensors when available as we think it is a good indicator of image quality.

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 GF5
or the
Panasonic GF3 ,
including hyperfocal distance.
