Older Olympus Zuiko OM Lens Question

    I recently got the OM-4/3 adapter and picked up a used 50mm F3.5 Macro lens
    to play around with. I have a question as I never used older Olympus Zuiko
    lenses (my older 35mm equipment was Minolta).
    On the on the chrome part of the lens nearest to the camera/adapter there
    are two buttons. One releases the lens from the camera/adapter. The other is
    just to the left of the F numbers and for the life of me I cannot figure out
    what it is supposed to do. (I can't find any information on Olympus' site
    describing the functions of the older lenses.)
    Can anyone help? Thanks

    That is your depth-of-field button. All OM lenses have it.

    You might be interested in an article by Mike Johnston, on the Luminous
    Landscape web site, where he mentions what appears to be your very lens as
    being quite good. He even has photos.

  8. He's referring to the 50/2 macro, one of the sharpest lens ever. It holds its
    own against the Summicron 50/2.

    You have two choices. The adapter he mentions is for the Olympus E-1.
    There is also an independent company that makes an adapter to the Canon EOS
    mount, allowing the Olympus lenses to work on a Canon body, including the
    10D, etc.

    Both, unfortunately, work in stop-down metering mode. I own a large
    collection of Zuikos, but couldn't live with stop down metering.

    Does anyone have an idea where this adapter might be available? I'm in
    the Netherlands and just purchased an E-1. Since I own quite a bit of
    nice OM-glass, I'm quite keen on the possibilty of using some of it on
    the E-1, but the adapter mentioned above doesn't seem to be available
    over here.

    Maybe I can get it from the US by mail-order. But on the few sites I
    checked so far (Tristate, B&H and 17th Street Photo), I couldn't find
    any reference to it.

    Any information would be very welcome!

    It is not available for purchase. In both the US and Japan, Olympus is
    providing the adapter for free to registered owners. I don't know about
    Europe.
