Lens note: There is no information available about this lens, so this is just a guess.
We think it's a black type 50th anniversary model based on the shape.
The silver type has "E39" written on the front frame, but this one has "462" written on it.
(Probably the production number is one of the limited edition of 500 or 1000 pieces.)
If you have any information, we would greatly appreciate it if you could provide it.
