Concerning dismantling lenses in order to clean
helicoids, diaphragm
blades etc. you might be interested in Chuck Cole's opinions as
expressed in the ManualMinoltaFree Yahoo group. Somehow I imagine you
might disagree with him, or else you might explain your method of
dealing with the issues he feels so strongly about...
Well, if he's suggesting spaying soemthing into the lens (yes, I have
seen that suggested!), I certainly disapprove. If he;'s suggesting
removing the optical elemenets and applyuing solvent/lubricantmix to the
mount, then that's slightly better, but IMHO that's a method used by
people who can't handle tools and small parts properly, and if you're not
careful, it simply shifts the gummy lubricant, etc, elsewhere where it
will cause toruble lateer. I really do prefer to clean each part separately. In fact the last thing I recall him getting het up
about re threads
was that he believes only special lubricants should be allowed near a
lens, and that what's suitably for a focussing screw wouldn't be the
I wouldn't go that far. I think the generic focusing grease avaiable
from, say, MicroTools would be OK on most lens helical threads. Actualy,
I've used normal high melting point grease there with no problems.
