Olympus E-M5 III vs Samsung NX20 Sensor Comparison

		

		

			
Normally, its difficult to visualize the difference between sensor dimensions only by reading through specifications. The image below will help offer you a better sense of the sensor measurements in the E-M5 III and NX20.
Plainly, the 2 cameras posses the exact same megapixel count albeit different sensor dimensions. The E-M5 III has got the tinier sensor which should make obtaining shallow DOF more difficult. The more recent E-M5 III should have a benefit with regard to sensor innovation.
