just got my canon elan II this morning. man this thing has more buttons and settings than this polock has ever delt with. I ordered a magic lanterns guide to my camera to help me learn how to use everything to it's fullest. Now i just need an adapter for my contax lenses to work on my elan body. I have seen some on ebay for around 20 bucks shipped. my question.. should i order one from a camera shop, or should these work fine? also, does anyone use polarizing filters with black and white photography?
