Clearly, both of these cameras have different megapixel count and different sensor sizes. The E-M5 III using its smaller sensor is going to make achieving shallower depth of field more challenging and the Olympus E-M5 III will produce more detail with its extra 4MP. Higher resolution will enable you to crop shots a bit more aggressively. The more recent E-M5 III should have an advantage when it comes to sensor technology.
