I have been using SLR film cameras for years, but have not done too much with them for a few years (long story). I have moved into the digital SLR world and my old EF lenses will fit my new digital Rebel XT. The question I have is - do filters age? I have UV filters for all my older EF lenses and was wondering as I try them out in the new digital world, whether or not I need to buy new ones? Thanks in advance for any insight anyone can provide.
