Focus problem in AF-S NIKKOR 28-70mm 1:2.8 D ED and other details

This AF-S NIKKOR 28-70mm 1:2.8 D ED had a focus problem because one of the circuit board was coming off the dubble side sticky tape, and that way the focus scale was hitting the circuit board. but it was "easy" to fix with another piece of strong dubble side tape that carpenters use, and now it work's perfect again.
