Both Olympus E-M10 II and Panasonic G5 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-M10 II and G5 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus E-M10 II and Panasonic G5 Cameras
Olympus E-M10 II and Panasonic G5 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-M10 II and Panasonic G5 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-M10 II has scored 73, 12 points higher than G5.

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-M10 II
or the
Panasonic G5 ,
including hyperfocal distance.
