The Adaptall-2 Tamron 24/2.8 (01BB) is a high-quality and compact manual focus option for 24mm. That said, there is a common problem with the lens in that the plastic window over the distance scale has a tendency to pop off, leaving the lens with no focus/aperture index mark and no DOF scale. Below is my copy with its errant distance window.
I would really like to see it back into its place and while it is easy to find reference to the issue on the Web, it is more difficult to find verified suggestions for a suitable adhesive. What I know:
- It was originally attached at the far ends only with something that turned gooey with age
- The curve of the window is tighter than the curve of the lens body, making it behave as a spring when attached.
- Cyanoacrylate is not an option (will etch the window and other stuff).
- Epoxy is an option, but I am concerned about and cleanup.
- Weldbond is mentioned in several places, but with no actual success stories to back the suggestion.
What say the good folk here? Has anyone had success doing this?
