Usually, it can be hard to visualize the contrast in sensor sizing just by seeing a spec sheet. The visual here will give you a far better sense of the sensor dimensions in the E-M10 III and E85.

Clearly, each of these cameras come with different megapixels and different sensor sizing. The E-M10 III because of its larger sensor is going to make shooting shallower depth of field simpler and the Olympus E-M10 III will show more detail having its extra 4 Megapixels. Greater resolution will make it easier to crop photos a good deal more aggressively. The more modern E-M10 III provides a benefit when it comes to sensor innovation.
