Both Olympus E-M10 II and Olympus E-PM2 have 16.0 MP resolution sensors but Olympus E-M10 II's sensor is Four Thirds (17.3 x 13 mm ) and Olympus E-PM2's sensor is Four Thirds (17.3 x 13 mm ).
Since Olympus E-PM2's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Olympus E-M10 II.
Below you can see the E-M10 II and E-PM2 sensor size comparison.
Olympus E-M10 II and Olympus E-PM2 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
