I bought a new 12-32mm as part of a split kit on eBay back in August 15 and through lack of use I sold it through eBay. Unfortunately when the buyer tried to use the lens the following happened: I searched through the forum and couldn't see any threads on this, which I'm surprised at because there are a few posts on DPReview. The buyer returned the lens to me and I've since put it back together. With the zoom ring pushed on the zoom still works, but it feels loose and the zoom ring can be easily pulled off. I've cleaned off some horrible black grease from the underside of the zoom ring and then reattached the zoom ring using double sided tape. The zoom ring now feels pretty solid! I'll now need to find a use for the lens, a bit frustrating as the money would have been useful.
