Clearly, each of these cameras feature different megapixel count and different sensor sizes. The D20 due to its tinier sensor will make shooting shallower DOF more difficult and the Canon D20 will give extra detail as a result of its extra 2 Megapixels. Greater resolution will also let you crop pics way more aggressively. The younger D20 will have a benefit in sensor technology.
