As you can see, the 2 cameras offer the same exact sensor sizing but not the same MP. You can expect to see the Olympus E-M1 III to offer extra detail as a result of its extra 8 Megapixels. Greater resolution will also make it easier to crop pics a little more aggressively. The more modern E-M1 III is going to have a benefit in sensor innovation.
