I bought a Vivitar 200mm f/3.5 because everybody was raving
about them.... but it wasn't even as good as my M 80-200 f/4.5
zoom, although that (the zoom) was better than an M 200mm f/4
I had. The only 200mm's worth bothering about seem to be the
ones with ED glass... link

Some Pentax lens tests here....

Wine isn't just for breakfast time you know

The push-on rubber lens hood is well worth having it
extends the MF grip and is so rigid that you can
actually turn the end of the lens hood. Very rare
but did come with the lens. Fits any 58mm filter
lens. 60mm push fit.

It's a pity they didn't make more push-on hoods,
they are a lot quicker to put on and remove than
screw or bayonet hoods.

They seem to be done on film and written by Ken Norton
I wouldn't take too much notice of them

On the Vivitar 200mm f/3 Series 1 he gets the best performance at f/16

Nice One!

One Magnifying 1.35x Eyepiece sold to RyanK.

thoramay... you have a PM

I managed to get 5 of these so I have 2 to spare if anyone
wants one. £28 posted.

A few people on here have been asking about presription
eyepieces KPS also do a Universal Eyecup Set which looks
the same as the magnifying one except that it has a
plain glass lens. The idea is that you can replace this
(or even replace the magnifying lens on the other
model) with a prescription lens. The lens should be
15.3mm diam. and up to 3mm thick.

I've got one of them, but can't do it any cheaper than
£25 posted, but you would have in next day and not
have any import duty to pay.

Don't forget the big advantage in allowing anyone to sell.

There have been a few bereavement sales like that and
Unlocker got his 250-600mm like that at a very cheap
price

I'll finalize and collect in the morning. I've just agreed to
take all 4. I want 2 of them and I can do the other two for
£28 each inc. postage which is cheaper than Taiwan and no
import duty etc.

One's reserved for Thoramay the other one is available if
anyone wants it. They are new in sealed bubble packs
and it's the KPS 1.35x version.

Thoramay I'll send you a message in the morning.

There's a good thread on the US Forum about them as
well as this one here.
