    How do I identify/differentiate Contax SLR AE and MM lenses?

    Thanks! Chris

  2. Usually MM lenses have the smallest aperture in GREEN. But to be sure
    check the back end of the lens. It should have a small latch which engages
    a pin on the camera body. Check this link to see what pin I am taking
    about.

    When engaged, this pin allows the camera to operate in program and shutter
    priority mode. Actually, you can trick the camera to do that even when
    using an older AE lens. All you need to do is put a small piece of paper
    to hold the pin in place. I have tried this, but it is not recommended as
    the aperture mechanism on AE lenses is bulky and you could actually over
    load some camera components and break them.

    Hope this helps.

    I actually kept a copy of your post about this "trick" on Shuttercity.com.

    Just curious, do you have to hold the pin down on the body or just engage as
    you mount the AE lens?

    MM lenses have the smallest aperture number in green and also have a
    small tab on the lens that AE lenses do not have. The tab makes contact
    with a small button on the camera.

    The few times I tried it I just put a piece of Scotch tape over the pin
    on the body to keep it down. It is not recommended because reports say it
    might damage the camera.

    Subject: Re: Contax SLR AE and MM lenses
    This is nonsense. The only thing that should be green is the minimum aperture
    of the lens which denotes its an MM Contax lens as opposed to a standard AE
    Contax lens.

  8. I have tried this couple of times to check if it works but I advise NOT to
    do it.

    Anyways, if you still want to try it. I used to push the pin down and
    shove in a small crumbled peice of paper behind it to keep the pin rotated
    down.

    Try this at your own risk.
