It's an all-in-wonder lens, which means it's full of optical compromises. It's also a push-pull zoom, which most people hate. Make sure you try it out before you commit to anything. My one experience with it left me more annoyed than anything else. It has a tension ring to keep the lens from telescoping out when the camera is pointing down. I could find no "right" amount of tension and ended up having to constantly adjust it. It was a major pain in the ass. YMMV.
