While the A3100 IS might not have much in the way of features, it does have excellent photo quality for the money. Like many compacts in its class, there's a noticeable shift in quality at ISO 400, so the A3100 IS performs its best below this sensitivity. In other words, the more light you have the better off you'll be. Unlike its linemate, the A3000, this camera has less visible noise when photos are viewed at 100 percent. Combined with its higher resolution, you get a little more flexibility when it comes to larger prints and cropping.
