As you can tell, the 2 cameras have different megapixel count and different sensor sizing. The G2 having a smaller sensor is going to make shooting shallower depth of field tougher and the Sony A7 III will result in greater detail using its extra 12MP. Greater resolution will also make it easier to crop pics a bit more aggressively. The older G2 will be disadvantaged in sensor tech.
