Zuiko MC lenses

Dear friends
when started the production of the Zuiko MC lenses?
Is possible, from the serial number, to know the production's year?
I'm sorry for my English.
Thank You.
Giovanni

Giovanni,

I will try to give a short answer to your question. The OM system was introduced in 1972. A few of the original lenses were Multi-coated and most had single coating. For example, the 35mm f 2.0 was multicoated and the 50 mm f 1.4 was single coated. Other lenses were added to the system at later times and quit a few originally had multicoating. Some of these were the 24mm f 2.0 and the 21mm f 2.0. By the early 1980's, Olympus was using Multi coating on almost all lenses.

It is difficult to tell if a lens is multi-coated based only by serial numbers. I believe that Olympus had a policy of making improvements continuously and these "improvements" were not talked about very much.

I hope that this helps, perhaps others will also answer.
