As you can see, both of the cameras have different megapixels and different sensor measurements. The E-PM1 having a tinier sensor is going to make achieving shallow DOF trickier and the Pentax K-5 IIs will give more detail because of its extra 4MP. Higher resolution will allow you to crop shots a bit more aggressively. The older E-PM1 is going to be behind in sensor technology.
