Typically, its hard to see the gap in sensor dimensions only by checking out a spec sheet. The image here might provide you a far better sense of the sensor dimensions in the E-M10 III and E-P3.

Clearly, each of the cameras provide the same sensor dimensions albeit not the same MP. You should count on the Olympus E-M10 III to provide extra detail as a result of its extra 4 Megapixels. Higher resolution can also make it easier to crop shots more aggressively. The more recent E-M10 III will have a benefit in sensor innovation.
