As you can tell, both cameras provide different megapixel count and different sensor measurements. The E-M5 III because of its larger sensor will make shooting shallower DOF less difficult and the Olympus E-M5 III will offer you more detail due to its extra 6 Megapixels. Greater resolution can also make it easier to crop photos more aggressively. The fresher E-M5 III is going to have an edge when it comes to sensor innovation.
