Nikon mount experts needed!

Discussion in 'Nikon' started by Phil, Squid-in-Training, Jul 15, 2003.

  1. Hi all. This ISN'T spam. I'm selling a Nikon-mount Vivitar lens on eBay,
    and I received the following question from a bidder:

    "What nikon mt is this for I need it to fit a nikon fg i think it is Ais???

    My experience is with EOS, not the old Nikon mounts I'm selling... So I
    don't know exactly what mount this is, but it fits just fine on a Nikon EM
    camera. I thought Nikon never changed their actual mount... they just added
    contacts and stuff.

    The pictures of the lens are here: (This shows the mount itself)

    So my question is, how do I answer the bidder? Thank you so much!

  2. It looks like a first generation Vivitar Series 1, made by Kiron for
    Vivitar. It's a 1977 design, but this particular lens appears to have
    been made in 1981.

    IIRC, this is an AI lens, not an AI-S. But the FG was designed to
    work with AI lenses, even in program mode, so it should meet your
    potential buyer's immediate needs.

  3. It's an AI. AIS lenses have a little semi-circular groove
    on the face of the mount - the camera has a pin that senses
    the groove in order to determine if the lens is AIS.

    The FG does not have "Program" mode.

    However, it does have Aperture Priority
    AE mode, for which the extra features
    of AIS are not needed.

  5. Sure it does. It was the first Nikon camera with
    P mode. Its cheaper cousin, the FG-20 does _not_
    have a program mode, though.
