Title: Good lens, did not last very long.
Review: Bought this lens back in February 2006. I am an hobbyist photographer and used this lens often. I take care of my equipment, everything is kept clean and in a Canon backpack case.A couple months ago it started to get noisy when zooming. Now it will not zoom at all. At the time I paid 80$ for the lens, it would cost me 100$ to have the lens fixed. I have 2 other lenses that I got around the same time, a Canon and a Tamron that are still working.Have heard from others that Sigma's have lost their build quality, will not buy another Sigma lens.
