As you have seen, each of the cameras come with different megapixel count and different sensor dimensions. The E-M5 having a larger sensor will make getting shallow DOF simpler and the Olympus E-M5 will offer more detail using its extra 4 Megapixels. Greater resolution will make it easier to crop images a good deal more aggressively. The more aged E-M5 is going to be disadvantaged in sensor technology.
