I recently purchased a Pentax K-5. Apparently there are third-party adapters for mounting Adaptall-2 lenses on a Pentax mount.
Do you know of anyone that has ever converted the Tokina Nikon mount to Adaptall-2?
Thanks.....R
Adaptall mounts (The brand is Tamron, and in those days they made *everything* in Adaptall mounts, AFAIK: and as far as I know, Tokina did *not,* cause that was a proprietary Tamron thing. Actually, there was a *Tamron* SP series, is that what you have?)
If you have an Adaptall lens, you can get the appropriate Adaptall mount for Pentax and it'll fit right up. That's why they called em 'Adaptalls.' If the lens is made with its own Nikon mount, Adaptalls of any kind won't help you.
Adaptall lenses were made to *exchange* mounts, not add them onto another. (ie, you'd take *off* the Nikon-Adaptall mount, get a Pentax-Adaptall mount, and put that on there. Off and running. See? )
(Incidentally, btw, I *believe* the Tokina is a valuable lens in any mount: if that's what you have, it probably wouldn't be too hard to work a trade.
)
Oh, and where's my manners. Welcome!
