This is the best lens I have ever used. I've been using DSLRs for almost 10 years now and this is the best lens I've ever used. The lens has an impressive range that almost eliminates the need to carry multiple lenses around unless you're trying to photograph something miles away. This lens also improved the image quality of my Nikon D5000, which was only 12MP. The autofocus is very quiet and more accurate than my Nikon 55-200mm lens. Below is a shot I took with a new lens on the Nikon D5000. I'll let the picture speak for itself.
