Good starter lens

I bought this lens a few months ago and used it on a Canon 10D and now I'm using it on my 400D. I like the lens and it has a good focal range but the biggest problem I've noticed is it's focusing inconsistency and it's very loud focusing motor. If you shoot MF most of the time, it really doesn't matter on either of these issues but I'm not always shooting MF, mostly AF.

The macro feature is great but it's not a true macro lens. Detail is skewed at wide open and there is a rather narrow field of view but if that's what you're looking for, then it's a great lens.

This lens is also built like a tank. I like the fact that Sigma includes a lens hood with the lens and like I said, the build quality is terrific.

I'm about to sell my copy for a Canon 17-40 f/4L. Once you go L, you'll never go back!
