That's an unwarranted conclusion. The coatings may be done
under direct Pentax supervision. It's even possible that the
elements are coated by Pentax, in a facility that they control.
It's even possible - although I'm not saying that it's being
done - that there's a "coating factory" somewhere that coats the
elements for Pentax and Contax badged lenses, and maybe some
others as well.
And who's to say that SMC is substantially different - or even
any different - than some other coatings? Remember, according
to some historians, Pentax and Zeiss worked on developing
multi-coated lenses together, so it's not too much of a stretch
to assume that, at least the CZ T* lenses are coated similarly
to the Pentax SMC lenses.
