So I've bought this sicor lense, the auction stated that it's a pk mount lense. I've tested it with my Pentax me super. It fits into the bayonet mount, but doesn't rotate.
I've bought multiple brands of that exact same lens, it's a Nikon f mount. That's my favorite landscape photography lens and I use it to shoot massive panoramas.
Sticky out bit makes me think it's Nikon Ai.
Thanks for the info. After some research it appears to be old non-AI nikon f mount. I don't have a body with that mount so I can't be 100% sure
