(1) Are you sure that none of the early fast/wides were not marked X.Zuiko
AND MC?
(3) I believe some of your 'never MC' list existed without X.Zuiko but were
not MC
(4) I'm not convinced any MC 75-150 were ever made.
Just my two cents.

> 1. Lenses marked "MC" are MC. Obviously.
> 2. Lenses marked "F. Zuiko" (or G. or H...)are single coated. Don't
confuse this with lenses marked S Zuiko (no period after the S), which are
"budget" or "consumer" lenses. Actually I'm pretty sure all of the S Zuikos
are MC because they are all later designs
> 3. Lenses marked just "Zuiko" with no leading character are MC. I think
this is a pretty reliable indicator, since even the earliest fast wides
dropped the leading "F." (or "G." or "H."). For example, my low serial
number 24/2 (silvernose) is marked as such.
> 4. Lenses I believe were never MC: 28/3.5, 55/1.2, 135/3.5 I thought the
75-150/4 was never MC, but I'm not so sure after Lee's recent post.
> 5. Lenses I believe were always MC: 21/2, 24/2, 28/2, 28/2.8, 50/1.2,
50/2, 90/2, 100/2, 180/2.8, 250/2, 250/2, 28-48/4, 35-70/3.6, 35-70/4,
35-70/4AF, 35-70/3.5-4.5, 35-70/3.5-4.8, 35-80/2.8, 35-105/3.5-4.5,
50-250/5, 65-200/4, 70-210/4.5-5.6, 85-250/5, 100-200/5, 20/2 macro, 38/2.8
macro, 135/4.5 macro
> 6. I've never seen a Zuiko that had green reflections and definitely
wasn't MC. I've also never seen a Zuiko that didn't have green reflections
and was MC. Admittedly there are people out there that have seen a lot more
Zuikos than I have.
