   I am pretty sure what Woody meant was a wobbling from
side to side of the lensboard while focusing. In my
experience, from using the wrong lubricant on a camera, this
is due to the focus cam mechanism as I described. Since the
lens board does not necessarily stop in a parallel condition
its IMO a problem which should be fixed.
   The parallelism of the lens board itself, as you know, is
adjusted in all up to the F series by shims between the lens
board and the support, and the front panel is again shimmed
to make it parallel although this has no effect on the lens.
   I suspect actual loss of alignment of the lens board is
pretty rare and I suspect mostly the result of incompetent
repair work.
   I think Woody's camera needs some attention. Perhaps list
members can find a suitable repair person who is accessible
to him.

thank you belcher and Knoppow.  i think i have to mostly agree with
Knoppow's opinions.  the problem is, by your help, can i get contact
with a repair person accessiable to me? i currently live in Guangdong,
China.

to belcher,

i think i can not tell what is front panel and what is lensboard. they
seem attached together and when go wobbling.
