    Is the problem that the lens goes part of the way on, and then won't
    come back off? If so, the problem is that it has a small protrusion that
    sticks in the screw hole of the mount. You'll have to find some kind of
    very, very thin tool to insert in there. A tiny screwdriver won't work;
    it has slip between the mount faces.

    I happen to live in a house with a printing press in the basement, so
    there was no shortage of thin shim-like tools to poke in there. (These
    tools are used during book repair to separate glued paper from its
    backing without tearing it, so they're *thin.*)

    In my case, the lens was a Ricoh manual focus zoom. I located the
    offending nub and removed the tiny circuit board it was connected to.
    It's rude to post to usenet and ask for an email reply.
