Hi Angel:

There is a give away marking on the "MC" marked 50mm f/1.8 which tells you
it's the 6 element in 4 groups design and grew by 1 mm in length over the
older 6 element in 5 group design.  It's the 1 mm thick aluminum ring base
side to the depth of field and mount release buttons.  Modern Photography (May
1983, page 94) claims the change happened in 1979.  I think they were wrong.
FWIW, Olympus literature supports October, 1980 as a closer date to when it
made it to market.
