Title: Excellent all-around lens for DSLR
Review: This is the "kit" lens I got with my 40D. I've found that this is a great lens to use for most general purposes, especially for portrait and other "people taking" opportunities. As everyone else has mentioned the quality, optics, etc of the lens is great and the IS feature really does work surprisingly well. On a less than full frame sensor camera you'll may miss the wider angles provided by the other "kit" lenses (18-55mm or 17-85mm) if you're a Realtor or need to take a lot of wide angle shots (even so, 17mm times the crop factor isn't that wide), but I think this lens more than makes up for this in its utility at the telephoto end.
