Hello,
Am putting a Vivitar S1 28-90mm back together and thought to clean and re-lube the focusing threads.
What grease should I use?
It looks like some sort of grey colored grease on there now, perhaps graphite.
Thanks. |

You should avoid any grease which is based on mineral oil.
I have used silicone grease with good results. Micro-Tools sells different grades of dampening greases which should be just as suitable. |

Hi,
I have used a synthetic lithium grease with good effect. Micro-tools do list a variety of greases but they are priced way over the top IMHO. I obtained my grease from work. I can find the details if you wish.

Hi,
you will want a grease that is very stabile over age, that doesn't harden (oxidation) and doesn't fraction into oils that pollutes lenses, shutterblades and iris. You will want a grease with a very high temperature range that doesn´t go stiff in severe cold or starts migrating when warm.
One option may be a special helicoid grease called Klüber Catenera KSB 8. Just bought some - will let you know if this is the answer when I have had a chance to try it out.
Best regards,
Fredrik |

I bought a tube of Nyogel 795A from micro-tools and it is the best thing I've tried. Although $15 for a little tube seems high, you use so little of the stuff that a single tube will last a very long time. IMO it's worth it. I also use it on speed cams and aperture control rings on older cameras that don't have a click-stop. The damping action helps keep them from getting bumped out of position.
Nye products can also be purchased from TAI (www.lubekits.com). |
