As you can see, both cameras come with different megapixel count and different sensor sizing. The A390 using its bigger sensor will make getting bokeh simpler and the Sony A390 will render more detail because of its extra 2 Megapixels. Higher resolution can also allow you to crop pictures a good deal more aggressively. The younger A390 will have an advantage with regard to sensor tech.
