Gary,
It might be difficult to narrow things down, because I think that Olympus
listed discontinued equipment as is it were still around. For instance I
have a 34 page brochure titled, Olympus OM System, whose date on the back
cover is 0187, and it lists 6 available camera bodies, OMT, OM4 Black, OM3
Black, OM2S Program, OM1, and OMPC. --I don't think so.
The introduction to the Zuiko Lens Group says, "...special new optical
glasses, multicoating techniques, etc. help give*every*Zuiko lens an extra
edge in performance..." Multicoating is not specified for any particular
lens. It implies that they all are.
I have put a plus(+) mark by each lens in the list that is listed in the
brochure. There are no additional lenses mentioned in the brochure.

The following page (unfortunately undated) describes the
