Originally posted by LyleC Thanks for the quick replies. I tried one last time before returning it ( I have 30 days) and managed to get the barrel moving and the zoom to work - perhaps just jammed a little. I'll play with it for a few days more before deciding whether to return it or not. Focus motor seems to work fine and so does the focusing ring. Thanks again.
"Just jammed a little" is not good... a modern digital AF lens shouldn't jam under normal conditions.
It could be the outcome of a fall or a bump, all things who could have had an effect on lens alignment as well.
I'd return it, my 0.02c
