Both Olympus E-PL5 and Panasonic GF6 have Four Thirds sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the E-PL5 and GF6 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-PL5 and Panasonic GF6 Cameras
Olympus E-PL5 and Panasonic GF6 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
Both Olympus E-PL5 and Panasonic GF6 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, E-PL5 has scored 72, 18 points higher than GF6.

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
Olympus E-PL5
or the
Panasonic GF6 ,
including hyperfocal distance.
