• Canon AE-1 Program Lens Stuck

    I know these aren't the most active of newsgroups, but perhaps
    worth a try...

    About a year (or was that two...) ago, my Korean made "Kalimar"
    zoom lens became stuck on my Canon AE-1 Program. It had always
    been difficult to get on (not off) since I bought it second-hand
    a few years earlier. This last time though, upon removal I was
    only able to rotate the lens ring some of the way before it became
    stuck in a loose state where it wouldn't rotate back to the
    "locked-in" position, or allow the lens to be removed.

    So far I've tried undoing a few of the screws on the lens around the
    comera end, but they didn't offer any improved access, and in final
    desperation I tried brute force applied from various angles, but no
    change resulted (except for an unfortunate dent). I had a look
    through two service manuals on the web for the AE-1 Program, but
    they didn't inspire any further ideas.

    Luckily I had another AE-1 (non-program) which I've switched now
    instead. But it's a frustrating way to loose a camera, so any
    suggestions on how to bring the "Program" off the shelf and back
    into service would be appreciated.

    Are you in Sydney, Australia?
    If so, take the lot to Camera Service Centre in the CBD,
    here is their website and location/phone:

    http://www.cameraservicecentre.com.au/

    Over the last 10 years they have been second to none in fixing all my
    lenses and cameras, at a very good price and superb quality of work.

    I'm not familiar with the lens, but if the relevant screws are set
    screws holding the outer ring to some moving part, _tightening_
    may be the direction to go.

    Thanks, but the whole lens body turns with the ring on this lens.
    Wikipedia informs me that this is the "New FD" mount, but should
    still work with the AE-1 (as it did before it got stuck). I just
    had a check of the screws anyway, but they seem in well enough.

    I never found an exact match for this lens online, but doing a
    wider search now it seems that it was sold under a range of
    different brand names, with range of different mounts: https://www.pentaxforums.com/userreviews/kalimar-18-28mm-f4-4-5-mc-auto-zoom.html
    http://allphotolenses.com/lenses/item/c_3412.html http://m42lens.com/m42-lens-database/1527-sirius-mc-auto-zoom-18-28mm-f-4-4-5-22

    Perhaps that explains why the KD mount design might not have
    been as refined as one would hope.

    Thanks, but I'm in country Victoria and I don't think there
    would be any places nearby who would still handle film cameras.

    I realize I'm a little late with this reply, but sometimes the simple
    answer is the correct one. The new FD lens differs from the old
    lens in that the new FD has a button on the lens ring that must
    be depressed to remove the lens. You probably know this,
    but still...

    Thanks. I do have a Canon lens with such a button, but this one
    is without one. The only button is one on the appature ring
    which has to be pressed before moving the appature control
    to automatic mode. In case I'm loosing it I just gave it a try,
    but it doesn't help.

    Thanks, I've spent a while in the past searching around web forums
    for similar problems reported in old threads. I don't like joining
    and checking web forums though, and in this case my motivation stops
    short of doing so.

    Oh dear, I can't spell aperture it seems...

    to automatic mode. In case I'm loosing it I just gave it a try,
    but it doesn't help.

    Actually, after working it a bit, the lens ring does rotate about
    1mm against the lens body (the entine lens body rotating about
    10mm on the camera's lens mount). The degree of rotation that the
    ring has seems unaffected by the romoval of the (previously
    tightened) screw that goes into it on the outside.

    Perhaps I didn't mount it by turning the whole lens as I remember,
    or perhaps the ring was jammed and turning the whole lens to mount
    it was the fatal mistake, or maybe the ring is meant to be fixed
    in place and is just a little loose.


    Actually, if I turn the lens leftwards on the mount and set the
    aperture to the maximum f stop (F22, it won't move over to the auto
    position), it won't rotate back near as far to the right. If I push
    it, the aperture ring stays stationary and changes setting as the
    lens rotates (which sets it to about F8). So it seems that the
    aperture lever that connects with the camera is caught somewhere.

    I'll have a closer look when I have more time.

    You are trying to loose it but having no luck.
    You may be losing it.
