    Anyone recognize this?

    I thought it was a T-mount, and seem to recall getting the Nikon adapter
    for it used from a camera shop but it is not threaded, just a tapered
    49mm flange/slip fit. The adapter slips over it and three set screws
    hold it firm while the taper on the male part of the lens prevents it
    sliding off if slightly loose. This is from Century Precision Optics,
    likely built for cine/movie use but last owned by a film 35mm photog.
    It's fine on FX. Perhaps a proprietary mount?

    Excellent, thanks. More recently I ran into threaded M42 'Universal
    screw mount' ot 'Pentax screw mount', which I understood to be T-mount
    but I obviously had it mixed up. M42 won't quite go to infinity on a
    Nikon mount, I got a 125mm lens to focus to about 20 feet away at
    infinity focus. The T-mount has plenty of room for any 35mm SLR mount.

    There is also a T2 mount with tighter thread pitch and it includes
    another connection that allows rotating for best operation and
    flexibility on a tripod. I've not seen those.

    That sounds like the T2 mount. Tighter thread pitch and sort of half way
    between T-Mount & M42.


    Yeah, that's what it is. I didn't know T stood for Tamron.
