I hope that you will be able to give some advice.
I have the above lens in excellent condition,it is the AI mount and made towards the end of the production run around 1981.
The lens as been used only a couple of times over the last year and when cleaning it yesterday I noticed it had developed a creak on the focus ring. The creak seems to be intermittent and not always in the same focus area.
What would you think the cause of this may be and is there a fix?
Thank you.
