Plainly, each of these cameras offer different megapixel count and different sensor sizing. The E-520 with its tinier sensor is going to make achieving bokeh more challenging and the Pentax K-7 will offer greater detail because of its extra 5MP. Higher resolution will make it easier to crop photographs a little more aggressively. The older E-520 is going to be behind with regard to sensor tech.
