Do you know what bayonet mount this is ?

[_goodtimez]

I have this lens in my lot which I bought at a flea market but I cannot recognize the mount.
It's not Nikon, Canon, Minolta or Pentax (I tried).
Any suggestion please ?

Are you sure it's not Nikon F mount? It looks very like it ! I've just compared the back with the back of one of my Nikon lenses.

You're right ! how could I miss this ...
I was distracted by the absence of the coupling prong, but this converter is oviously for later models.
So I just double checked on a Nikon EM and it fits 🙂
Many thanks

The AI pusher block on the outer rim is the best clue when the prong is not there. Nikon was the only OEM to use that method.

The Minolta MC/MD system is very similar but works the other way as the SR mount twists clockwise to go on unlike the Nikon mount.
