Looking for either a new, like new or mint+ proper lens cap for a Canon FD 50mm f1.4 lens. This would be from the AE era of cameras. It is a 52mm cap. If you are a Canon person, you know which one I need. I'm not interested in the caps for the more modern lenses and don't need another one that is not new, like new or mint+. I have some of those. Thank you, Bill Barber
