Canon R3 vs Olympus E-M1 III Sensor Comparison

		

		

			
More often than not, it is very hard to visualize the contrast between sensor dimensions merely by reviewing a spec sheet. The pic below will offer you a better sense of the sensor sizes in the R3 and E-M1 III.
Clearly, both of those cameras have different megapixels and different sensor dimensions. The R3 using its larger sensor is going to make getting shallower DOF easier and the Canon R3 will deliver extra detail with its extra 4 Megapixels. Greater resolution will also let you crop photos a bit more aggressively. The more modern R3 provides an advantage when it comes to sensor tech.
