Message: <blockquote data-quote="ceasar" data-source="post: 3223645" data-attributes="member: 26155">Bruce,Will the guy you contacted at Zeiss put that statement here on Bird Forum in writing for you?  It changes the entire abbreviation system for the type of coated lenses that I and other people have become used to using.  In my experience FMC has always meant "fully multi coated" and MC meant "multi coated" which is why I responded to your question about where I found it by saying that I took Zeiss's printed statement in the TerraED manual to mean multi-coated.  I wasn't trying to be snarky about it.  You asked me about where I got my information.    I think that the  Zeiss rep should come on Bird Forum and clear that up if Zeiss considers MC to mean "fully multi coated."   How can people have a discussion about the relative merits of mid priced binoculars if we can't speak with precision about how they are constructed?   Swift spelled it out in full on their various Model 804 binoculars so there was no confusion.   What would happen if another company decided to tell us that "when we say that that our lenses are 'coated' we mean 'fully multi coated!' "  There have to be standards when discussing optical coatings on an optics forum. Who is the Zeiss rep?  I forgot his name.  He was answering some questions put to him here a while back about the Terra ED I think.  Bob</blockquote>
