I have a Nikon 55-200mm DX auto focus lens. I recently repaired the bayonet mount myself - all went well. But when I went to use the manual focus option on the lens, the focus ring remained locked, as it is on autofocus. Any suggestions as to what I need to do to fix this?

    \$\begingroup\$ "I recently repaired the bayonet mount myself - all went well." Not to sound mean, but I don't think that sounds like the case. Modern lenses are much more electronic, I think you should probably look to have it serviced by Nikon. \$\endgroup\$

Sounds like the release from the AF motor is not functioning. I would recommend having it serviced by Nikon.

  • \$\begingroup\$ I have switched the A to M mode...and I am not sure if I did something to damage the man focus mode when I repaired the bayonet mount, or if this is a different problem, as I didn't try to manually focus until 2 months later.... \$\endgroup\$
