I was recently offered a Nikon d50 from an old school chum of my mothers, for a discounted price (and he also offered to throw in two lenses) while this was a great deal, I had another offer of just the Nikon d50 body for a significantly cheaper price. Since I already had a 35-80mm lens from our old Nikon f50 I was hesitant to spend the extra cash... Therefore here's my question, can I use the old film lens on the new digital camera? And if so, what are the side effects? Thanks! Leslie G.
