So my Canyon (sorry) 200mm F2.8 arrived.
It was very clean and a bargain price (~150) .
It seems very well made,compact and I like the IF.
First impression just holding it tightly against an adapter. (My MD adapter is
still coming) was results are not as sharp wide open, as I remember from the
OM180/2.8,that I had for a short period.
Need to wait for a real adapter and go and use it in the field to really tell.

Addendum:
Gary Reese listed the 200mm f5 MC too:
http://zone-10.com/cmsm/index.php?option=com_content&task=view&id=272&Itemid=97
Suspect the performance is vastly under-rated given how light it is.
Telephoto stabilizer doohickey or shot filled bean bag may do wonders
like on my Z. 50-250.
It doesn't appear very many were manufactured.
Key omission, Mike
CV180 f4: 485 gm 66mm X 59mm --49mm filter!! MFD 1.2m Max mag 1:4
bokeh very nice
Zuiko 200 f5 MC: 380gm 105mm X 62mm 49mm filter MFD 2.5m Max mag
about 1:10
Zuiko 200 f4 510gm 127mm long X67mm diam 55mm filter MFD 2.5m
The OM tilt-shift bellows requires a special order form the secret
Wyoming factory discovered by John Lind:

but the Z. 200mm f5 MC is slightly easier to acquire. I am 99% certain
Jeff K has one or two though they are hard to find.

I wouldn't have Big Foot's longer brother w/o help from this list.
Jeff is very very good at locating hard to come by items. (perhaps a
few more very's are in order) A CV 180 in OM mount even 5 years ago
was exceedingly tough to locate after they were no longer available NIB.
I looked diligently all over. Jeff suggested I contact an ebay seller
in HK directly as he seemed to list the occasional CV lens. I did
contact him and he kept his eye out at HK shops for used items, and one
in very nice shape showed up in less than 2 weeks for a good price no
less.

A lovely lens, as are its siblings. :-)

For tack sharp at normal distances, but not for compactness (and not
necessarily
for close work, as I haven't tested
that), my ancient, earliest version 200/4 Nikkor just flat whupped both
my 200/4
and 200/5, center and edge.

Do you think they really exist? I believe I've seen one pic of one
example, but
perhaps a prototype or mock-up? Back in
my active OM equipment gathering days, I never saw one for sale.

all). Did
I say it is small?
You did, and it is. :-)
I suppose part of the more complex optical formula (9-7 vs. 5-4) is to
allow the
shorter physical length. It's about the
same weight, if you include hood, as the Zuiko 200/4, and the same
diameter, but
considerably shorter. As with all
telephotos, the front lens node is in front of the glass, but further
in front
than with the Zuiko, and even more than
the Nikkor.
Now that's made me think, and check. The mount to front length of the
Nikkor-Q
is about 157 mm. Combined with the
register distance of 46.5 mm, that's over 203 mm, which puts the front
node
roughly inside the front element, not out in
front of the physical lens.
Perhaps the lack of much telephoto design is why the lens performs so
well with
such a simple optical design?
