As you can tell, each of these cameras have got different resolutions and different sensor sizes. The E-M5 having a larger sensor will make shooting shallower depth of field simpler and the Olympus E-M5 will produce more detail using its extra 2MP. Greater resolution can also let you crop pics much more aggressively. The younger E-M5 is going to have an advantage with regard to sensor tech.
