Sony A7 vs Sony A7R III Sensor Comparison
More often than not, it's difficult to see the gap between sensor sizes purely by reviewing technical specs. The pic underneath may offer you a clearer sense of the sensor sizes in the A7 and A7R III.
As you can tell, both of the cameras come with the identical sensor size albeit not the same megapixels. You can expect the Sony A7R III to deliver greater detail due to its extra 18 Megapixels. Higher resolution can also make it easier to crop shots a good deal more aggressively. The more aged A7 is going to be behind with regard to sensor tech.
