As you can tell, each of the cameras posses different megapixels and different sensor sizes. The E-M5 III having a smaller sensor is going to make achieving shallower depth of field tougher and the Panasonic S1R will produce greater detail because of its extra 27 Megapixels. Higher resolution can also make it easier to crop pictures somewhat more aggressively. The fresher E-M5 III provides a benefit when it comes to sensor tech.
