So, I am sitting pretty now with my three lenses, a 50mm 1.8, a 55-200 VR and of course, the 18-55mm kit lens. I am considering buying a wider/faster lens than the 18-55 which will make it obselete, since I ONLY use that lens at around 18-22. So what else can I do with it, besides making it a pretty neat paperweight? Is there a way to reverse it to do Macro? Any other neat DIY ideas?
