All in all, both of these cameras posses different resolutions and different sensor measurements. The E-M5 II with its tinier sensor is going to make achieving shallow DOF trickier and the Olympus E-M5 II will deliver more detail with its extra 4 Megapixels. Higher resolution will also allow you to crop shots somewhat more aggressively. The older E-M5 II is going to be disadvantaged when it comes to sensor tech.
