Sometimes, it is very hard to see the contrast in sensor sizing purely by going through specifications. The visual underneath should provide you a much better sense of the sensor sizes in the E-P1 and K-1.

Plainly, both the cameras feature different megapixel count and different sensor sizing. The E-P1 due to its smaller sensor will make shooting shallow DOF more difficult and the Pentax K-1 will provide more detail due to its extra 24 Megapixels. Greater resolution can also allow you to crop images way more aggressively. The older E-P1 will be disadvantaged in sensor tech.
