Sony A7 IV vs Sony a1 Sensor Comparison

		

		

			
Typically, it is very tough to see the difference in sensor sizes just by checking out a spec sheet. The picture here should offer you a stronger sense of the sensor sizes in the A7 IV and a1.
As you can see, both the cameras have got the exact same sensor measurements albeit not the same MP. You should expect the Sony a1 to produce more detail using its extra 17MP. Higher resolution can also help you crop shots much more aggressively. The fresher A7 IV will have a benefit in sensor tech.
