More often than not, it is very tough to picture the contrast between sensor dimensions purely by checking technical specs. The image below might provide you a stronger sense of the sensor sizes in the E-P3 and K-50.

As you can tell, both the cameras feature different megapixels and different sensor dimensions. The E-P3 featuring a tinier sensor is going to make shooting shallow depth of field more difficult and the Pentax K-50 will give more detail as a result of its extra 4 Megapixels. Greater resolution will also enable you to crop photos way more aggressively. The more aged E-P3 is going to be disadvantaged when it comes to sensor tech.
