Clearly, the two cameras have different resolutions and different sensor dimensions. The E-M1 using its bigger sensor will make achieving shallower depth of field simpler and the Olympus E-M1 will deliver extra detail having an extra 4 Megapixels. Higher resolution can also allow you to crop pictures a bit more aggressively. The more recent E-M1 is going to have an advantage in sensor tech.
