As you can see, both of these cameras come with different megapixel count and different sensor sizes. The E-M1 having a smaller sensor is going to make getting shallower DOF more difficult and the Sony A6600 will render more detail with its extra 8MP. Higher resolution can also allow you to crop photographs a good deal more aggressively. The more aged E-M1 will be behind with regard to sensor tech.
