Clearly, both of the cameras offer different resolutions and different sensor sizing. The E-M1 III using its larger sensor is going to make getting shallow depth of field easier and the Olympus E-M1 III will show greater detail with its extra 8 Megapixels. Greater resolution will also make it easier to crop photos a little more aggressively. The more recent E-M1 III provides a benefit in sensor innovation.
