The type 1 lens gives no indication of coating and has the front ring markings H.Zuiko Auto-W 1:2.8 f=24mm.
The type 2 lens seems to indicate a coating \"(C)\" and has the same front ring markings as the type 1 lens.
The type 3 lens indicates NMC (multicoating) and was made initially with the front ring markings: Zuiko MC Auto-W 1:2.8 f=24mm and subsequently Zuiko Auto-W 24mm 1:2.8.
Example pictures of the three versions:
type 1 or 2, I don\'t know how to distinguish which from the front ring markings:
type 3, first version:
type 3, final version:
The same reference listed above (olympus.dementia.org) also contains the line:
\"The first lenses that were labeled as such [MC] were the lenses that were never made in a single coated version: the 18mm/F3.5, 21mm/F2, 24mm/F2, 28mm/F2 and 35mm/F2 lenses. Strangely enough these lenses appear in early lens tables with the preceding characters but they were put into production the the MC inscription.
Fisheye lenses, Shift lenses, Zoom lenses and Macro lenses never carried the preceding characters.
Once multicoating was so self-evident, that all lenses were produced multicoated, the MC addition was also dropped and the lenses only contained the word ZUIKO.\"
I hope this is helpful information.
