Hello,
I am looking for someone techically inclined.
I was taking off the UV filters from my AI-S lenses to clean out dust, and some of them were well on there. I noticed some budging further down in the lens case. So I "screwed" it back (1-2 mm) and I ended up using a rubbery cord to hold the lens case while unscrewing the filter — worked fine.
Now my question is... what was that budging, what gave further down, is the housing screwed in? I am the paranoid type and fear that I might have caused damage to the lens. I know that AI-S are old stuff, but I am hoping someone will have some old school engineering knowledge.
By the way, the lenses seem to work all right.
