Hi all:
I did a bit of research and editing of the Zuiko multicoating list at:
http://www.astro.wellesley.edu/hawkins/photo/multicoat.txt
Here is the edited list. My apologies for messed up formatting, if any! I
can e-mail a text file without line breaks if desired.
I'd love to see us narrow down the years that lenses were discontinued.

July 30 1998 version
I hereby re-post a contribution of 1996/7/17 on the subject of multi-coating:
I tried to compare MC data of all Zuiko lenses I know of from some booklets
issued by Olympus. They are Manuals for the Zuiko Interchangeable Lens Group
(MZILG) as packed with bodies in earlier times, body manuals with lists of all
available lenses at time of publication in them, and the Olympus Lens
Handbook.
Dates of issue (month and year):
01-74 Manual for OM-1 (my first, the only one I ever bought new)
10-74 MZILG packed with OM-1 above
01-78 OM System Sales Information File
07-78 MZILG
01-79 Manual OM-2
03-80 Lens Group Manual
10-80 Manual OM-10 Q
02-81 Manual OM-10
12-81 OM-1 Instruction Booklet
01-82 Manual same OM-10 in French
04-82 MZILG
03-83 *
XX-84 Olympus OM Series Lens Handbook*
04-84 Olympus System Handbook
12-84 Olympus System Chart
04-85 Olympus System Chart
10-85 Olympus Lens Handbook
12-85 Olympus System Handbook
10-86 Zuiko Lens Leaflet
10-92 Olympus System Handbook
* The 1984 Olympus OM System Lens Handbook includes pictures dated March,
1983, in which lenses new to production were featured.
In next table I give date of first appearance and date of first mentioning
'MC' respectively

* there were two versions of this lens, manual and auto. The manual one had no
helicoid and the rubberized grip (usually the focusing ring) was the aperture
ring and the other ring was preset aperture ring. The write-up does not
mention the Telescopic Auto Tube which I take to mean it was not released at
that time (01-78). The following page (unfortunately undated) describes the
Zuiko MC 1:1 Macro 80mm F4 / Close-up lens 80mm Macro f=170mm. It appears to
be optically the same lens but with auto-diaphragm and rear elements
protruding far beyond the lens mount. I should think it safe to assume that
the manual version was SC and the auto version MC only. The Auxiliary lens
enabled the lens to achieve magnifications in range 1X to 2X in with the
Telescopic Auto Tube.

** Probably multicoated as of date of introduction. Stated to have "Always"
been multicoated in http://www.datasync.com/~farrar/zuiko.html
Please note that the dates must not be considered as starting (or ending)
dates of issue or MC feature. The time gaps between the
booklets I own are too wide for that. Maybe we can narrow the gaps? If we
only had a list of serial numbers and corresponding
dates of manufacturing...
I already corrected some obvious mistakes of the lens handbook myself.
Maybe I even missed a lens altogether...
Frank.
NB: According to Olympus America, the way to tell if a lens is multicoated is
to look at the writing on the front. If the lens has an
element letter (eg G.Zuiko) it is single coated. If it lacks the element
letter, and/or has MC on the front, it is multicoated.
