New to the list...looks to be a valuable tool in my forays into takumar land...
Anyone know anything about a sort of adhesive that holds the last 2 elements together in the Super-Multi-Coated Takumar 35mm f/3.5? I got one with fungus and took the last lens off, to see that it sort of tore away from the next one leaving a dried residue that was not previously visible, what I think was some sort of glue. I've resorted to scraping it off but can't get it all...would acetone work? Ideas?
