Hello Michiel,
Thanks for sharing the reply from Kindai International. I will continue to keep my eyes for Exakta Real Mount adapters. All the best, Leica 77
Good luck, but I doubt that you'll find much unless something was custom-made during the Real's brief period of existence.
As you know, the Real's lens mount is larger in diameter than the standard Exakta mount (46mm vs. 38mm, if I remember correctly.) So while it was possible to use standard Exakta lenses on a Real via the adapter you discovered originally (more or less a simple ring that made the mount larger in diameter) it would have been impossible to go the other direction and make the (larger) Real lens fit into the (smaller) standard Exakta mount.
So, all the scads of adapters made over the years for mounting the standard Exakta lens on various other cameras will not work with your Exakta Real lens, because the lens mount's diameter is too large.
To find an adapter to mount an Exakta Real lens to
anything, I would guess that your best hope might be Alpa -- the Alpa bodies were thin enough that many adaptations were possible, and they were active in the camera business during the brief period during which the Real was produced.
But even if you found one (and I have no evidence that they ever existed) then you'd simply have the different problem of finding an adapter to put an Alpa lens on whatever you wanted to use.
So you should have an interesting challenge ahead of you, to say the least!
