Even if your not thinking of modifying your current Canon lens to create a macro the video. Lozzless mesmerising video of him creating a super macro lens from a Canon 18-55 mm zoom kit has to be watched if only for pure enjoyment.
If you are thinking of doing this launch itself in the video explains every stage with beautiful detail but this mod is definitely not for the faint hearted as the mod involves disassembling the lens, using wires from a floppy drive cable just for starters. However the the finished super macro lens is awesome and able to be fitted to a Canon SLR and gives you full electronic aperture control.
