Clearly, both of these cameras have got different megapixel count and different sensor dimensions. The E-620 using its tinier sensor is going to make achieving shallower DOF harder and the Pentax 645D will give you extra detail with its extra 28MP. Greater resolution will let you crop images much more aggressively. The more aged E-620 is going to be disadvantaged with regard to sensor tech.
