My 28-70 f/2.8 is on my camera (D700, and since yesterday, D80 ) 95% of the time. I love this lens. I bought it used several years ago here on the "I want to sell" forum. The lens has been put through the mill, including a recent fall where the hood was shattered. It still performs like new.
However, he rubber gnarling on the zoom ring has come loose. It doesn't affect the lens operation except my having to push it back in place from time to time...of course, this usually happens when there is a lot of action I'm trying to capture.
This is something I feel I can "glue" back in place, but I don't want to use the wrong type of adhesive and damage the lens. I'd rather leave it as is than risk damage.
Obvious question is: what adhesive should be used to make this minor repair.
