With all the discussion about what lenses are MC vs SC, I thought I'd
try to summarize a little.
FIrst off, general rules. All of these assume there hasn't been a
front ring change due to a repair, in which case all bets are off.
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.
All your points, but this seem valid. My late production S/N 135/3.5
is marked exactly this way. Certainly don't think the front element is
MC with no color, e.g. known MC lens. Rear is the purple variety - -
SC or MC?? Discussion centers around either / or, i.e. SC/MC.
Suffice to say from looking at my lenses and posted material, MC had
several 'stages' or grades. More than SC, but less than all elements
coated. Yes/No??

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.
