I finally found a use for my 18-55 Canon kit lens. I glued a cut-up body cap to a heavy duty cardboard tube and stuck a reversed lens on the other end to make a decent (and cheap) macro lens. I threw the whole thing together in about 20 mins. with a dremel and some duct tape. The "N" in "Canada" on a Toonie: The tip of a wood screw: Enjoy!
