Olympus E-M1 III vs Pentax E85 Sensor Comparison

		

		

			
Quite often, it is very difficult to visualize the difference in sensor dimensions only by looking through specifications. The picture underneath may offer you a clearer sense of the sensor sizes in the E-M1 III and E85.
Plainly, both of the cameras offer different megapixels and different sensor dimensions. The E-M1 III using its larger sensor is going to make shooting shallower depth of field simpler and the Olympus E-M1 III will result in greater detail with its extra 8 Megapixels. Greater resolution will make it easier to crop photos a little more aggressively. The younger E-M1 III should have an edge when it comes to sensor innovation.
