Clearly, each of these cameras feature different resolutions and different sensor sizes. The TG-4 because of its smaller sensor will make achieving shallower depth of field more difficult and the Sony A7R IV will provide more detail having its extra 45MP. Higher resolution will make it easier to crop pictures way more aggressively. The more aged TG-4 will be disadvantaged with regard to sensor innovation.
