Febi 31942: application for lenses

I tried Febi 31942 as a lens grease.

I tested it on the Индустар (Industar) lens.

Compared to GM Special Lubricant High Temperature grease (which I also use in lenses):

1. Febi feels more viscous.

2. But the backlash of the focusing mechanism is the same as with GM.

3. The rotation of the focus mechanism is slightly uneven.

4. There is a smell, specific but weaker than with GM.

5.  I have not tested the operation in cold weather.

Overall, I don't like it very much, but it can be used if you have nothing else.
