Someone gave me a Vivitar Automatic Tele Converter but it does not fit my Pentax DSLR. I think it is a canon fitting but it looks a bit ancient. It says “Vivitar Automatic Teleconverter 2x-4 FL-FD” On the side of it. Is it worth anything?
Sounds like you need a Canon FD mount adapter. Not sure if you can get them for Pentax mount though.
Google is your friend 😀
