Clearly, each of the cameras provide different megapixel count and different sensor sizes. The E-510 because of its tinier sensor will make achieving shallower DOF trickier and the Pentax K-01 will give extra detail as a result of its extra 6 Megapixels. Greater resolution will also make it easier to crop photos more aggressively. The more aged E-510 is going to be behind with regard to sensor innovation.
