I am new to photography, and brand new to the Photo Forum. I recently purchased my first camera, a Canon EOS 20D. I do not have much money to purchase lenses yet, however I did inhert an older Canon (FTb QL) that has a 50mm UV lens, 28mm skylight (1B) and a massive C/FD lens. Is there anything I can purchase that will allow these lenses to work with my new Canon? Or is this a lost cause? I appreciate your feedback!
