I have a soligor lens and I don’t know what is the mount


The mount on your lens appears to be the one used by the Rolleiflex SL35 line of cameras. Rollei couldn’t be bothered to give the mount a name, so it’s unofficially known as the Quick Bayonet Mount (QBM).

The mount locks using a notched tab (A) when turned clockwise. Other common mounts that lock using a notched tab include Minolta SR/MC/MD and Contax/Yashica (C/Y). To differentiate them, it’s necessary to note the types and positions of other lens-camera linkages.

For QBM, auto aperture is controlled by a pin (B). Aperture setting for TTL metering is communicated to the camera via a tab (C).
