    This sure looks like a Canon EF mount, but there's too many contacts - anyone know just what it is??

    It looks like it might be a Sony Alpha mount, one of the later variants without the screw-drive autofocus.

    Pentax K-5, K-r, K20D, K100D Super. Canon Rebel XT (350D), Eos 100, 500, 600, T90
    Various OEM and 3rd party lenses in Pentax, Minolta and Canon.
    Looks like an EF mount to me, but I have only seen the old Minolta A mount on lenses. It will be interesting if it is a Sony and so close to the Canon mount.

    UPDATE: I purchased a different Sigma lens (18-200mm) but with the same contact layout (8 instead of 5) and it works perfectly on my 80D. So, not sure what's going on - maybe Sigma has some updated info from Canon??? Or the Sigma Alpha mount is a Canon clone???
    I'm just happy the lens I purchased works!! :)

    Tim, thanks for the link! I'm almost too embarrassed to admit that I actually have 2 of the lenses listed in the article as having the 'extra' contacts! :oops::D
