Plainly, each of these cameras come with different resolutions and different sensor dimensions. The WG-20 because of its tinier sensor is going to make shooting shallow DOF more difficult and the Sony A7 III will give extra detail as a result of its extra 10MP. Greater resolution can also make it easier to crop photos a good deal more aggressively. The more aged WG-20 is going to be disadvantaged with regard to sensor innovation.
