Olympus E-M1 vs Sony TX20 Sensor Comparison

		

		

			
Generally, it can be tough to visualise the gap between sensor sizes purely by reviewing technical specs. The pic here may offer you a greater sense of the sensor measurements in the E-M1 and TX20.
As you have seen, the 2 cameras have got the exact same resolution but not the same sensor sizes. The E-M1 uses the larger sensor which will make getting shallow depth of field easier. The younger E-M1 is going to have an edge with regard to sensor innovation.
