Plainly, the 2 cameras posses different megapixels and different sensor measurements. The A7 III featuring a larger sensor is going to make getting shallower DOF less difficult and the Sony A7 III will show extra detail having its extra 8MP. Greater resolution can also make it easier to crop photos somewhat more aggressively. The more modern A7 III should have a benefit when it comes to sensor tech.
