Anyone getting deep into fretting about different coating versions of
the 85/2 should be aware that this lens is unique among regular Zuikos
in having gone through an optical redesign that included a change in the
number of elements.
I think it went from 5 elements in 4 groups to 6 in 4.
Does that liven the issue?
Dang it, Moose. There you go again trying to throw in an on topic posting.
The Zuiko police may be giving you a call.
This could make for a real lively discussion if the change from SC to MC
occurred at a different time than the change in design.
By the way, Mannheim and Pangerl (both editions) have it at 6 elements and 4
groups. Pangerl calls the lens an "extended standard" lens, as opposed to a
telephoto. The OM System Lens Handbook (something every Zuikoholic should
own at least one copy of) has it at as a semi-telephoto with 5 elements in 4
groups. The copy of the dealers, "Olympus Sales Information File", I have
shows it as a telephoto in the 5/4 configuration. Shipman has it as a
telephoto. The Zuiko Interchangeable Lens Group booklets up until at least
10/78 show
it as 6/4, while the 9/79 printing show it at a 5/4 configuration. I am
clueless about coatings variants and will leave that to someone else.
Nothing like a little research project and OM list posting to keep you from
doing the other important things in your life . . . as if there were any.
Yes, there are. I'll post them when I figure them out. <{8^) Bill Barber
