Clearly, both the cameras have got different megapixel count and different sensor measurements. The Q7 having a tinier sensor will make getting shallow depth of field harder and the Sony RX100 III will give you extra detail because of its extra 8 Megapixels. Higher resolution will help you crop photographs much more aggressively. The older Q7 is going to be disadvantaged when it comes to sensor innovation.
