L4) What does MC mean? How can I tell if I have a multicoated lens?
Many early Zuiko lenses were single coated. Those that were
multicoated were denoted by the MC logo, until most of the lens
line was multicoated. Then the MC logo was dropped. It is
generally agreed that the presence of any green reflection, no
matter how faint, is evidence of multicoating, while predominatly
yellow reflections denotes single coating. Zuikos with the
G.Zuiko type designation are more likely to be single coated.

1. There are multiple versions of this lens (probably 5, according to people with parts lists). Some early ones have a radioactive rare-earth glass element. I hear it's not dangerous, but it can yellow with age. The last version of this lens (not rare-earth), with serial #s over 1,100,000, is reputed to be the best.
