Thanks for posting your diagnosis and repair tips, Bill. I had the same manual focus failure problem, and following your suggestion fixed it. I agree with your comments regarding the poor design. It's especially surprising to find such a careless design in an otherwise capable lens that's been in production for so long. I wonder if the spring tab attachment has been re-engineered in more recent samples. (Mine is about 10 years old).
