Hi,
I have this zoom which has a loose barrel, as you can see from the photos I am able to lift part of it (aperture ring is removed in the photo). This is as far as I've been able to get, I cannot see how to proceed and the barrel section is still loose (this is the part that I cannot find a way of removing, I have not loosened it by my dismantling). Any suggestions or advice? I have been told that this lens is not worth a great deal, but it would be nice if I could fix it. :D
I suspect it has been apart before as inside I found a bracket which I *think* came off the aluminium locking ring which secures the lens to the camera, but the two screws for the bracket were firmly on the ring.

Hi Jonny-
I also have a Vivitar 70-150 zoom but it doesn't bear any resemblance to yours. Vivitar sourced these lenses from a number of manufacturers. Mine is a one-touch and yours looks like a two. Loose barrels are usually the result of just a few screws getting loose and when tightened, the whole problem goes away.
If you want to dig in further, I would suggest that you remove the rubber "grips" over the two adjusting rings and see if a few screws show up in access holes. Just peel them back and take a look. In general, lenses of this type come apart into two main assemblies and that is where the loose screws are usually found.
But you are on your own in that decision as your mileage may vary. I don't have any specific experience with your lens, and can't take responsibility for it. Just take your time you stand agood chance of fixing it.
