As you can see, each of these cameras have different megapixels and different sensor dimensions. The VR-330 with its tinier sensor is going to make achieving shallower DOF more difficult and the Sony A7 will give extra detail using its extra 10 Megapixels. Greater resolution will also let you crop photos a bit more aggressively. The more aged VR-330 is going to be disadvantaged with regard to sensor technology.
