tony_estcourt Posted September 24, 2011 Share Posted September 24, 2011 <p>Hi - my 70-210 Tamron Adaptal manual focus lens is stuck on my D700. The lens releases but when I turn it the last few mm wont go and it wont release from the camera. Also the lens appears to be stuck in a manual aperture mode. I wont force it off, but before it goes to the repair shop has anyone else out there had this problem?</p> Link to comment Share on other sites More sharing options...
paul_wheatland Posted September 24, 2011 Share Posted September 24, 2011 <p>Carefully release the lens itself from the Adapt-all mount. Then try to determine why the mount itself won't release from the D700 body. Above all do not force anything. Saving that you may need to visit the technician, but at least the lens you can leave at home. Wrap the body in a clean freezer bag so dirt doesn't enter the mirror box and soil the sensor.</p> Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted September 24, 2011 Share Posted September 24, 2011 <p>I've had an apparently stuck lens myself. It turned out that the lens (an old Kiron zoom) was missing a small screwhead that prevents the lens from rotating too far clockwise when detaching the lens. Try rotating the lens or mount slightly anti-clockwise, as if attaching the lens, while pulling it forward. That's all I can offer.</p> Link to comment Share on other sites More sharing options...
tony_estcourt Posted September 26, 2011 Author Share Posted September 26, 2011 <p>Re-visited the lens today, and it came off as Rodeo Joe suggested. Elderly A2 lens is now a paperweight.</p> Link to comment Share on other sites More sharing options...

john_tighe1 Posted March 9, 2013 Share Posted March 9, 2013 <p>I just had an Adaptall 2 lens get stuck on my girlfriends D5000. I wasn't worried, but I was very concerned. The mount was an "AI" adapter. I was testing the 28mm f/2.5 and the Nikkor 28mm AF lenses on it. I had already shot a set of pictures with both, and had put the Tamron on for a second time when it got stuck. I can't believe that I would have been able to put it on wrong, but it was stuck in a manner that didn't look natural; the solution was to push down a black, spring-loaded tab on body. The black, spring-loaded tab at the "8 o'clock" position of the body mount was keeping a non-spring-loaded tab on the Adaptall 2 part from rotating, thus preventing the lens from unmounting. I took a letter opener, used that to push down the tab on the Nikon, then the tab on the Adaptall 2 could rotate past it.</p> Link to comment Share on other sites More sharing options...
