Re: [APML] Zenitar 16mm f2.8 "fisheye" - happy now

[Stuart Heggie <stuart.j.heggie@sympatico.ca>]

Hi all - the fix Dominic directed me to was exactly what I needed and
the lens is now performing really well. I had a little trepidation but
it all went smoothly. Also, the folks I bought it from were very
supportive and ready to do the honorable thing if I couldn't fix it but
encouraged me to try first of course. I advised them that they should
tell their factory to "focus" on QA issues they seem to have.

Anyway, in case anyone else had the same problem with their Zenitar, I
can assure you the hyperlink below did the job for me but I'd be happy
to offer help off line if that is needed.
