While I have the lens partly disassembled , I am thinking I should
go a bit further and change the lubricant for the focus, its really

which will work well in sub zero temperatures.

There isn't one. Go find a microscope place, and ask them for some
grease to use. Be nice and they will possibly give you the small smear
you need for free.

Do NOT even THINK of using normal grease or oil, it will coat the optics
and inner surfaces and trash the lens.

Some research seems to indicate that NYOIL or HELICAL GREASE are what I
need. Any thoughts on that Paul?


Maybe, I don't know the specific stuff you quote. Ring or visit your
local uni and ask one of the lab techs what they use, and where to get it.

The above seem OK though.
