    I mounted a Helios 81 (FSU) lens on a Nikon N2000 since it was the only 50 mm AI lens that I had. I ran one roll of film through the camera to test it and the combination worked fine. Now I find that the lens is stuck on the camera. Any suggestions on how to get it off. FWIW, this same lens mounted and dismounted without problems on my F90x.

    With past experience using Russian equipment, their tollerances in manufacture are sometimes different to those of the likes of Nikon/Canon/Pentax etc. It may be something as simple as the button used to unlock the lens on you camera body may not be being depressed far enough to release the pin. Also with it being a Nikon N2000 which is a Nikon 'clone' body, that is to say, not made by Nikon or under their control may be exaggerating the problem.

    As I recall the same body badged 'Olympus' with an OM Mount was made in China.

    To BMbikerider: are you sure about the N2000, otherwise known as the F-301, being a "clone"? I'm almost sure they were all made by Nikon in Japan.
    See here: http://www.mir.com.my/rb/photography/companies/nikon/htmls/models/htmls/slr8486.htm

    There is a difference between the manual focus F mount and the auto-focus mount. The ring, where the screw from the auto-focus motor seats, is wider than the manual bodies. But, that doesn't explain your problem.
    As said above, built quality for Soviet lenses varies a lot.

    If you want it removing without damaging the camera, take it to a camera repairer.

    ... and then throw away that russian lens. Or buy a Russian camera to put it on. As you are discovering, cheap doesn't pay.:wink:

    That's ok! :smile:
    And you were right on the ball with the manufacturing tolerances!
