Clearly, each of these cameras feature different resolutions and different sensor dimensions. The E-M5 because of its smaller sensor will make shooting shallower DOF more difficult and the Sony A9 II will render more detail due to its extra 8 Megapixels. Higher resolution will allow you to crop shots way more aggressively. The more aged E-M5 will be disadvantaged when it comes to sensor tech.
