As you have seen, the two cameras have got different megapixels and different sensor sizing. The E-P1 with its smaller sensor is going to make achieving shallow depth of field trickier and the Pentax K-30 will show extra detail having an extra 4 Megapixels. Greater resolution can also allow you to crop images much more aggressively. The older E-P1 will be behind with regard to sensor technology.
