<p>As an Exakta owner of old but not since the 70's, I would highly recommend the Meyer Telemegor 300 or 400mm but also any Tamron adaptall I or II telephoto with Exakta/Topcor interchangable mount. These are all affordable unlike Zeiss or Schneider,Kilfitt. I currently have a monster Tamron 200-500mm adaptall II lens which I like and many different mounts for it BUT it is huge. Tamron DID make adapters for their adaptall and adaptamatic lenses as well as T-Mount teles. The adaptalls would give you auto stop down (you wouldn't have to focus stopped down) BUT if you go that route buy the correct adapter first as Exakta adaptall adapters are hard to find, even online. They are cheap . T-mount adapters are even cheaper(I have 3 for exakta)</p>

<p>Sorry, The "adaptor N" was a Canon FD adapter to use Nikon lenses on a Canon FD body.So no help for your question.</p>
