As you can see, both of these cameras enjoy different resolutions and different sensor sizing. The E-P1 due to its smaller sensor will make getting shallower DOF more difficult and the Olympus E-P1 will produce more detail due to its extra 6MP. Higher resolution can also enable you to crop photographs far more aggressively. The younger E-P1 is going to have an edge with regard to sensor innovation.
