As you can see, the 2 cameras enjoy different resolutions and different sensor dimensions. The Q-S1 due to its smaller sensor is going to make getting shallower depth of field harder and the Sony A9 II will provide greater detail having its extra 12MP. Higher resolution will also allow you to crop shots far more aggressively. The more aged Q-S1 will be disadvantaged when it comes to sensor technology.
