Fujifilm X-S20 vs Sony A7 III Sensor Comparison

		

		

			
Typically, it is very difficult to see the difference in sensor sizing only by checking out technical specs. The visual below will help give you a stronger sense of the sensor measurements in the X-S20 and A7 III.
As you can tell, the 2 cameras offer different megapixels and different sensor sizing. The X-S20 with its smaller sensor will make getting shallower depth of field tougher and the Fujifilm X-S20 will produce greater detail with its extra 2MP. Higher resolution will allow you to crop photographs a little more aggressively. The younger X-S20 will have an edge in sensor technology.
