I tested several other lenses on the camera body in question and all of
them focus to infinity. I guess it could be the *ist-Ds so I'll try in
on the D and one of my LX's or MX's just to make sure, but I'm pretty
sure that I eliminated the body as a problem when it could focus the F
70-210 to infinity and I was able to focus the Vivitar S1 70-210 to
infinity later.

Subject: SMC A* 300mm f4.0 no longer focuses to infinity!
Just what the subject says. I was out walking with a relatively full
kit and I spied what I thought was a Cormorant, but turned out to be
what looked like a diving duck of some kind. I mounted the the F 1.7x
adapter and the A*300, and couldn't achieve focus.
I thought it was the adapter, but after much fooling around, I was able
to confirm that the A* 300 can no longer focus to infinity. Even when
racked in to it's further focusing distance. The focusing scale says
it's focused at or beyond infinity but the focus point seems to be about
200/300 yards/meters away.
I've used this lens to good effect for the last few years. So this
problem seems to be a very recent development.
Physically the lens seems to be rock solid. The helical moves from
minimum focus to infinity as smoothly as ever, shake it nothing rattles
yet there is something obviously wrong with the lens.
So does anyone know of a good lens repair place in the US, it's a cinch
that Pentax won't repair it, and the only good camera repair place I
personally had experience with has long since dried up and blown away.
(It would also help if they didn't charge an arm and a leg for repairs
since my budge is down to one or the other).
