Title: Great, while it lasts.
Review: This lens takes absolutely fantastic photos. I've used it with both a Rebel and a 40D with amazing results. So why only 1 star? Within 1 month of the warranty expiring the auto-focus abruptly died. Seems to be a common problem with this lens (check out the flikr reviews). Anyway, great lens... that will need to be replaced often. If you wanted to keep purchasing a good lens, this is the one for you.
