To sum up, each of the cameras have different resolutions and different sensor dimensions. The E-PL2 with its tinier sensor is going to make shooting bokeh tougher and the Pentax K-S1 will resolve more detail having an extra 8 Megapixels. Higher resolution can also allow you to crop shots a bit more aggressively. The more aged E-PL2 is going to be disadvantaged with regard to sensor technology.
