    I bought this 500mm mirror lens really cheap in a second hand store - probably to re sell on eBay but do any of you know what mount it is?
    the lens is a sirius 500m reflex f.8- it seems they were made for different mounts
    Thanks in advance

    Ah yes... i did not notice it unscrews to reveal T2 (is this the same as an m42?) mount. The adapter even says "for Pentax K/M on it. Thanks!

    NO ! ! ! ! ! !

    The T/T2 thread is different than that of the M42 mount. Attempting to fit a T/T2 lens to a M42 body will damage one, the other, or both. Also, the mounts' register distances are quite different.
