[QUOTE="D200freak, post: 511558, member: 41018"] I'm working on a preventative fix right now which can be done in a few minutes without any major lens diassembly. I predict it will work but I'll know for sure later this evening. You need a piece of shim stock about a quarter inch square and about 1/32" thick. Metal or plastic. Carefully pull off the zoom rubber grip and then remove the black plastic band under it, which is just taped on. Carefully pull the tape off the sliding contact and carefully remove the sliding contact. Remove the two screws visible in the zoom ring. Now rotate the ring to the 135 position and CAREFULLY pull it off. You will find that there are two copper spring plates (two pairs, actually) on the back side that you will have to reinstall later. Now insert a fitted, snug fitting plug (the 1/4" square piece I mentioned) into the slot where the metal piece is that has two screw holes in it. (You just removed those screws to get the ring off.) Put that filler piece at one end of the ring so that it restricts zoom travel at the short end. Reassembly is the reverse of the process. Getting the metal tab to slide to where you need it won't be difficult. You'll figure it out. Those copper springs can be reinstalled through the longer portion of the slot where the contact fingers came from. Rotate it around, you'll see where they go in their own little recesses. You can also slide those springs in from the inside of the ring as you slip the ring back on, but that is harder to do and get everything properly aligned. The ring has to be oriented to about the 135 position to be pushed into its proper place. [/QUOTE]
