Hello Marco,
your message is one week old, but I want to say something concerning it.
The company Pentax has bound itself to multicoat every element in lenses
which are named SMC. Some not fully multicoated Pentax-A lenses they called
Takumkar-A. Olympus says in publications that multicoating should be
practical or useful from the technical viewpoint. I have tried some Pentax
lenses in my photographic life, and I think, that multicoating doesnt help
these lenses in all cases.
