Clearly, both of those cameras feature different megapixels and different sensor dimensions. The A9 II using its larger sensor will make achieving shallower depth of field less difficult and the Sony A9 II will render greater detail because of its extra 8 Megapixels. Greater resolution can also allow you to crop pics way more aggressively. The younger A9 II is going to have an advantage with regard to sensor tech.
