Plainly, each of these cameras offer different megapixels and different sensor sizing. The E-3 with its tinier sensor is going to make getting shallower depth of field more challenging and the Pentax K-7 will offer you more detail having an extra 5 Megapixels. Higher resolution will help you crop shots a little more aggressively. The older E-3 is going to be disadvantaged with regard to sensor technology.
