As you have seen, the two cameras enjoy different megapixels and different sensor dimensions. The E-420 because of its tinier sensor will make achieving shallower depth of field trickier and the Pentax K-5 II will deliver extra detail having its extra 6 Megapixels. Greater resolution will also help you crop images far more aggressively. The more aged E-420 is going to be disadvantaged with regard to sensor technology.
