The black piece is glued between the big lens element and the small lens element on a swing arm. I think you can use virtually any glue which is suitable for non-porous surfaces. When using superglue, NEVER apply it directly. Believe me, even if contacts look perfectly clean they sometimes are NOT. My job as an electronic design engineer would be much easier if bad contacts were so easy to detect... I would strongly recommend cleaning the contacts with electronic contact cleaner, use a 'tuner spray' if possible. Moisten a q-tip with this fluid and wipe the contacts gently several times. It seems as if the f/16 contact is dirty since you get such a leap of exposure time when changing from f/11 to f/16. |
