Clearly, both cameras posses different resolutions and different sensor sizing. The E-620 with its tinier sensor will make getting shallower DOF more difficult and the Panasonic S1R will resolve greater detail with its extra 35MP. Greater resolution can also make it easier to crop photos somewhat more aggressively. The older E-620 is going to be disadvantaged with regard to sensor tech.
