Quite often, it's difficult to imagine the gap in sensor sizing just by viewing technical specs. The photograph below will provide you a better sense of the sensor sizing in the E-PM1 and K-70.

As you have seen, the two cameras have got different resolutions and different sensor sizing. The E-PM1 featuring a smaller sensor is going to make achieving shallower DOF harder and the Pentax K-70 will provide you with more detail utilizing its extra 12MP. Greater resolution will also enable you to crop photos much more aggressively. The older E-PM1 will be disadvantaged in sensor innovation.
