The 28 mm f/2.8 was introduced in December 1980 in MC version.  It replaced
the 28 mm f/3.5 (always single coated) which was discounted in February, 1981.
The 100 mm f/2.8 dates are the same as in:

which are introduced as single coated in January, 1974 and first mentioned as
multicoated December 1981.
