There are 5 types of 50 1.8
1 - Silver nosed, single coated
2 - black filter ring, single coated, glass parts different than type 1.
3 & 4 multicoated. "Japan" on name ring. Mostly identical inside
except type 4 has different lens group 2nd in from the rear. Name ring
will say "MC" (type 3) or not (Type 4).
5 - Multicoated, "Made in Japan" on name ring, shares no optical parts
with type 3 or 4. Uses same name ring as type 4, Not marked MC.
There are finer differences between the lenses, other folks may want to
go into those things.
