As you have seen, the two cameras provide different megapixels and different sensor measurements. The E-M5 II featuring a larger sensor is going to make getting shallower depth of field easier and the Olympus E-M5 II will give greater detail due to its extra 6 Megapixels. Greater resolution will enable you to crop photos more aggressively. The fresher E-M5 II provides an edge when it comes to sensor technology.
