If you have an EF-S camera, you don't want this lens, you want to 55-250 IS lens which is a *much* better piece of glass. It's actually sharp at 250mm and the image stabilization makes hand held shots at max tele practical.
Cheap
Not a good lens; The optics are not very good; Mine is only anywhere near sharp at max tele if and only if I use F/11; Even a half stop up or down from there and it gets fuzzy; The lack of image stabilization makes it hard to use at f/11 except on a very bright day
