Casio EX-S7 vs Sony A7S III Sensor Comparison

		

		

			
Oftentimes, its hard to visualise the gap between sensor sizing only by going over technical specs. The photograph below might provide you a greater sense of the sensor sizing in the EX-S7 and A7S III.
As you can tell, both cameras have got the exact same MP albeit not the same sensor sizing. The EX-S7 has the tinier sensor which is going to make obtaining shallower DOF more challenging. The older EX-S7 is going to be disadvantaged in sensor innovation.
