All in all, both of the cameras have different resolutions and different sensor dimensions. The E-M1 III having a larger sensor is going to make getting shallow depth of field less difficult and the Olympus E-M1 III will give greater detail with its extra 4MP. Greater resolution will let you crop images a bit more aggressively. The younger E-M1 III provides a benefit with regard to sensor innovation.
