Clearly, both of those cameras provide different megapixel count and different sensor measurements. The Q due to its smaller sensor is going to make shooting shallower depth of field harder and the Sony A7 III will produce greater detail due to its extra 12 Megapixels. Greater resolution will also enable you to crop images more aggressively. The older Q will be behind with regard to sensor technology.
