I was unexpectedly given one of these lenses today. I would love to know more about it. Apart from its history, can you tell me anything about it as a lens? Its optical qualities? Can I get an adapter to mount this lens on a current Canon?
I also have an unusual UV filter and adapter - no rubber hood. It is mounted on a Bessamatic CS which so far appears functional. I need to find out about replacing the battery.
Would truly appreciate any feedback and information.
