Plainly, both cameras enjoy different resolutions and different sensor measurements. The E-M5 III featuring a bigger sensor is going to make shooting shallow DOF less difficult and the Olympus E-M5 III will give more detail as a result of its extra 4 Megapixels. Higher resolution will enable you to crop pictures far more aggressively. The more recent E-M5 III should have an advantage in sensor innovation.
