I had some problem with the front cover and hood on my Asahi Super-Takumar 135mm/3.5 m42-lens. The front “hull” or what you might call it, wobbled… including the filterthreads and the hood. Didn’t affect the imageproperties of the lens (the glass didn’t move) but annoying to use.
This turned out to be easy…
- Unscrew the ring where the lensname is printed. That’s just a ring screwed down in the filterthreads. Take a round object with smaller diameter then the 49mm filterthreads, cover it with a rubberglove or something that’s soft but has friction. Press down and unscrew the name-ring.
- The front hull of the lens is atteched with three small screws. Tighten the small screws you see down between the hull and the lenses glass.
- Reattach the name-ring. Done!
Here some pictures I took while doing this:
