    The only way I open a Leica lens is by sending it to a trained technician.
    When I grow up, I want to be a photographer.

    I agree, that is really the best option.

    My late friend Sheldon Brown designed
    a precision instrument for just this purpose:



    Get a good grip, and just reef on it
    Should do the trick

    I successfully opened a Mamiya lens years ago. Ended up sending all the pieces in a box to Paul Ebel so he could put it back together.

    Taking pictures is easy. Making photographs is hard.

    This guy and some high explosives should do the trick, along with a pipe wrench, of course..

    Generally, you must remove the face ring. But it depends on the lens. If it has slots, you can use a spanner wrench. Otherwise, you can use a rubber plug.

    However, some lenses aren't easily disassembled and require special tools.

    Upon reassembly, you should recollimate the lens.

    Sheldon's Tork-Grip also functions as an inertial impact alignment tool.

    As for cleaning the lens cells, the diaphragm, and collimation, it is next to useless.

    I'm pretty sure DAG is much less expensive than a genuine Tork-Grip.

    TORK-GRIP Universal Torque Wrenches are not available in any store,
    only on the Internet! Order Yours Today!!!
