Query: A very good travel lens at a great price!

I can't believe the price of this lens, vs. the features and quality. Believe me, I owned more than 25 lenses, 1/3 of them are Canon L lens. I know this is not the best quality compare to L, or even some top performers in none L category, but the quality is sufficient for everyday use.Look, the lens is small, light weight and offers a great range on focal length. With sufficient optical quality, mount it on your little Rebel camera, it beats the point and shoot camera at any time and even at similar cost in a sense.One think I want to point out is that the lens does auto focus at f6.3, at least on XTI, T3i and 7D which I tested. In most cases, f5.6 is the limit, but somehow this one works at f6.3. I don't know why.Get this lens, and add a 50 or 85 prime. That's all you need for most situations.
