Re: FD 24 / 1.4 lens, play in focus ring?


5. Turn the aperture ring to f16 and, with any tool, turn the aperture control fork fully anti-clockwise until it stops (this lens has a metal stop at the smallest aperture.





8. Mark on the metal piece on the aperture ring, the position of the back edge of the last aperture control fork.



9. Use the metal piece as a template, make a new metal piece. It will has an extension to push the aperture control fork, and its front edge will be correspond to the the last edge of the fork.



p.s. the front edge of the new lever should just touch the back edge of the fork *when the fork is fully anticlockwise and aperture ring is at F16*. Trim the lever or its two mounting holes to position it accurately.
