If this topic hasn't been beaten to death, revived, strangled, beaten and
kicked again enough, here's more points to ponder:
I've got a 1950's vintage Rolleicord TLR that reflects both lavender and
pale blue in both the taking and viewing lenses, yet there's no way that
it's evidence of any sort of coating. Plain ole glass can reflect some
funky colors. Optics are often seen as purplish, or bluish.
For the sake of keeping the OM language clean and meaningful, I suggest
that "Multicoating" be applied only to lenses that obviously reflect green
regardless of wheter earlier Zuikos may or may not have ever been variously
coated otherwise. That way, when somebody posts about an experience with a
multicoated lens, we'll all know approximately what is being discussed, and
likewise when such a lens is advertised forsale, we'll all be speaking a
common lens lingo.
