As you can tell, each of these cameras provide different megapixels and different sensor sizes. The E-M1 III having a bigger sensor is going to make getting shallower depth of field less difficult and the Olympus E-M1 III will result in greater detail with its extra 6 Megapixels. Higher resolution will also enable you to crop pictures more aggressively. The newer E-M1 III should have a benefit with regard to sensor tech.
