I have an Asahi Takumar 1:3.5/135 Preset lens (M42).
For an optical experiment, I need to reduce the outside diameter of this camera objective slightly (it's already a very small 135/3.5 lens but still a few mm too wide).
Is it possible to remove (preferably reversably) the aperture and preset rings (see arrows below)?
There are no grub screws anywhere on the outside of the lens. I would have to "go in" either from the back or from the front. What would you recommend?
P.S.: I tried to post an image (800x533 px, 164 KB); I can see it in the preview but not in the post. What am I doing wrong?
