    So I just bought this ancient 500mm lens from an antique shop for $5. Any idea what this lens mount is? I am having no luck finding it. I am hoping on adapting it to a Sony a6000. IMG_20190115_193349314.jpeg IMG_20190115_193342305.jpeg IMG_20190115_193402915.jpeg

    I think it might be a "T-mount" lens...meaning it has an interchangeable rear mount that is held in place by some small, set-screws. Not sure on this, but there does appear to be a set-scre in the one photo.

    The show rear mount has a _female_ characteristic to it...and it looks to me to be a Canon FD mount style, with the three, female receptacles.

    Not familiar with Canon lenses... It looks similar though. It's weird because the lens has the female end, which I have not seen before.

    Interesting. I was wondering about the small screws... The metal has different sheen to it on the part that could be the interchangeable portion. I was hesitant to take the screws out because I didn't want to make it unusable. Might have to get bold and just try it. O guess it's only 5 bucks though...

    I there are multiple set-screws that hold the rear mount in position, it is almost certainly a T-mount lens.

    HERE is a current Velo-branded T-mount, for Sony E-mount cameras. Price? $13.50. "T-mount lens to Sony E-mount camera." Do you see how this system works? It's super-simple, and was used a LOT in the 1970's and 1980's, especially on common, third-party lenses, like 500mm f/8 mirror lenses, and other long-length lenses. The lenses were designed so that the specific T-mount could be put into position on the rear of the lens, and ONE,single lens design could be made adaptable to many,many types of cameras.

    I think Derrel's nailed it! But I wouldn't touch the set screws just yet.
    with all the T2 lenses I've had the mount simply unscrews. T2 is a M42x0.75mm thread with 55mm registration.
    The 3 set screws are just used to align the lens, the adapter is usually in 2 parts a threaded core & an outer mount.

    It should be easy to adapt to your Sony, either using FD-NEX or T2-NEX options. :)

    $5 should prove a bargain price for it, especially as it has a hood.

    If you take apart a camera or lens and remove those tiny screws, you may want to put it all on a towel or cloth as you work on it. You don't want those tiny screws to bounce...
