I think you've got a Minolta A-mount lens. Compare to this photo (image borrowed from here):

Minolta A-mount

Minolta and Konica merged at some point and were subsequently acquired by Sony, and this mount is apparently still used by Sony as the "Alpha mount system".


It is a Minolta mount! Have a Look at the rear cap of this lens. (If you still have) There you should see "For ..."

    Which one? A-mount, SR-mount?

This is the Sigma SA mount. https://en.wikipedia.org/wiki/Sigma_SA-mount

which is like a cross between the pentax K mount (mechanically) and the canon mount (electronically)
