As you can plainly see, both of these cameras have different resolutions and different sensor measurements. The E-P2 because of its smaller sensor will make shooting shallower DOF more challenging and the Panasonic S1R will result in extra detail as a result of its extra 35 Megapixels. Greater resolution will also make it easier to crop images a bit more aggressively. The older E-P2 will be behind with regard to sensor tech.
