I really know nothing about different lenses, but if I were to get two, what would be my best options? Right now I only have the one that came with my Rebel xsi (I guess 18-55mm), and would like something with much more zoom. I think I only need one new lens, since besides the lack of zoom, I don't find anything wrong with this stock one as far as quality goes. I'm not exactly a demanding photographer.
