Panasonic G6 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Olympus E-5 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic V+ processor.
Below you can see the G6 and E-5 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic G6 and Olympus E-5 Cameras
Panasonic G6 and Olympus E-5 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 Olympus E-5 has 30% larger pixel area (18.45µm 2 vs 14.12µm 2 ) compared to Panasonic G6, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Panasonic G6 and Olympus E-5 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, G6 has scored 61, 5 points higher than E-5.

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 G6
or the
Olympus E-5 ,
including hyperfocal distance.
