    This is a Vivitar 135mm lens that I bought on eBay for $17. The lens is clear and clean; but what does it fit?

    As far as I can tell from the picture, it is an Exakta mount lens.

    And/or Topcon (as suggested by the "TOP" on it). Apparently Exakta and Topcon are practically the same, though I've never actually used a Topcon.

    Ivor Mantanle wrote about the Topcon in a recent issue of Amateur Photographer. He said that Topcon adopted the Exakta mount.

    Yes but...

    The lens in question has (if you imaginarily rotate it so that it is perpendicular), has:
    1) A stop at 4-o'clock - typical for Exakta (and apparently Topcon lenses) which locks it in.
    2) A lever at 7-o'clock, which does not exist on any Exakta mount, but should clear the Exakta bayonet.
    3) A lever at 9-o'clock which seems very close in (as far as I can tell from the picture) and *could* interfere with an Exakta bayonet.

    I would be glad to hear from anyone with any real experience with Topcon lenses....

    Thanks all. I bought it without paying attention to what it fit. I'll probably put it back on ebay.

    *****Topcon lenses could be used on Exaktas and the other way around; but they had to be used upside down.
