Be wary of the Canon Lenses that claim to be the Wonder lens offering Zoom Telephoto Macro Fisheye all from one lens.

I bought one as i'm new to digital and thought....wow one lens does it all, but beware the main lens is a Canon, and usually a cheap one at that, but the rest is just third party adons, the macro is distorted and worthless, just get a Canon lens with macro capabilties you will get better results and the fisheye is a waste of money, think how many times do yo want to use it! You can do a lot better for the money then these lenses, just search a little deeper!

Basically, look closely at what your buying, some things are not as good as they seem.
