Summary: I have had this lens for a few years now and have been very happy with it. For a DX Body it's hard to find anything this wide in the price range and of this quality. I have used it mainly for landscape and cityscape photography and have been very pleased.
Summary: Was teetering between 3 and 4 stars. This is a very good lens. I love the extreme wide angle (very hard to get on a crop sensor camera), and the build quality is very good. The zoom action and autofocus aren't Canon quality, but then, neither is the price.
