All in all, each of the cameras posses different resolutions and different sensor sizes. The E-P1 having a smaller sensor is going to make shooting shallower DOF harder and the Pentax K-70 will show greater detail with its extra 12 Megapixels. Greater resolution will also let you crop pics somewhat more aggressively. The more aged E-P1 will be disadvantaged with regard to sensor tech.
