A slightly later Super-Multicoated-Takumar or, later still, SMC Takumar
would probably be a better bet still, since Pentax's SMC coating is to
this
day one of the very best. (The original SMC is as good as modern Zeiss
T*
and Fujinon EBC, the current SMC I think edges even both these out.)
However, the latest Super Takumars were multi-coated before the process
was
officially launched by Pentax, so take a close look and you _may_ find
you
get a bargain if the lens has multicoating but not the 'label' to say so.

Actually during the late 1960s and early 1970s Pentax and Zeiss were
partners in many developments ophthalmological equipment and lens coatings
were just two areas. The SMC and T* were a result of that co-operation.




Actually Pentax licensed the technology from an American firm. They were
the first to use it on lens elements. Zeiss and Pentax were rivals in the
60s.
