I've not personally seen one, but there are brochure listings of fast wides
(always mc) with element letters. I believe this is also true of the
180/2.8. The element letter / MC equation seems to work for lenses where the
coating strategy changed, but is only an approximation. The actual marking
was market - driven. Originally Oly were following N*k*n with element count.
At the time this was supposed to be the indicator of quality. They then
switched horses to following P*nt*x with MC markings, as this was the
flavour of the month. Eventually they grew up and just marked the lenses as
Zuiko, and let the brand be the indicator of quality. The actual coatings
did not always follow the branding, so...
If it's marked MC - it's MC
If not, it may be MC, you need to look. Some lenses got all the way from
X.Zuiko to Zuiko without passing go. egg 200/5 and 135/3.5. Some of these
are MC (allegedly - I've never found one).
Some lenses got MC and X.Zuiko, even when they started as SC. I have an
X.Zuiko 50/1.4 which is MC (but different from those marked MC)
Some lenses got re - formulated at the time of going MC, egg 85/2.
Then there are repairs and upgrades. Makes you want to: 1.Weep. 2. Collect.
Thank goodness that Oly were less prolific in versioning than most..
