As you can see, both of these cameras offer different megapixels and different sensor sizes. The E-M10 III because of its larger sensor will make getting shallower DOF simpler and the Olympus E-M10 III will deliver greater detail having its extra 2 Megapixels. Greater resolution will let you crop photos a little more aggressively. The more modern E-M10 III is going to have a benefit when it comes to sensor tech.
