Tokina RMC 400mm F5.6

[J. C. O'Connell]

Recently bought a screwmount Tokina RMC 400mm F5.6
lens even though I already had the Pentax
Tele-Takumar 400 F5.6.  The main attraction for me
was for the auto aperture ( The Pentax is
manual aperture). To my surprise it's very compact
and doesnt get longer as you focus close.
I guess the focal length gets shorter as you focus.
It's shocking sharp in my initial tests. Keep
an eye out for this one, it's a winner.
(Paid $125 ebay for it).
