This is one of the best lens bargains that Canon offers. In my case, although I have a full complement of L, and near-L, lenses for my 1D-and 5D class bodies I wanted a small, lightweight tele-zoom for use with my new XSi body. Mainly on the strength of recommendations here I bought this lens, which has since exceeded all of my expectations.reviewed September 2nd, 2008 (purchased for $250)
No, the lens is not built like Canon's L lenses. But it's not priced like them, either. Frankly, I'm very happy wit its build. It's quite sturdy with nothing rattling or loose-fitting. The polycarbonate structure makes the lens nice and light.
If you're looking for a tele-zoom for your cropped-sensor Canon dslr look no further (and spend no more) than this baby. You won't regret it.
