Nikon Z9 vs Olympus E-M5 III Sensor Comparison

		

		

			
Quite often, its tough to picture the contrast between sensor sizing simply by checking a spec sheet. The visual underneath will give you a far better sense of the sensor sizing in the Z9 and E-M5 III.
Clearly, both the cameras come with different resolutions and different sensor sizing. The Z9 featuring a bigger sensor is going to make achieving shallower depth of field less difficult and the Nikon Z9 will give you extra detail due to its extra 26 Megapixels. Higher resolution can also help you crop pictures a good deal more aggressively. The newer Z9 should have a benefit in sensor innovation.
