          Olympus E-M5 II vs Sony A77 II Sensor Comparison
Quite often, it's difficult to picture the contrast in sensor sizing purely by researching technical specs. The photograph here will help give you a much better sense of the sensor sizes in the E-M5 II and A77 II.
As you have seen, both of those cameras come with different megapixel count and different sensor sizing. The E-M5 II using its smaller sensor is going to make shooting shallower depth of field trickier and the Sony A77 II will render extra detail using its extra 8 Megapixels. Greater resolution can also let you crop images a good deal more aggressively. The more modern E-M5 II provides an edge with regard to sensor innovation.
