Need help identifying a couple lens mounts

hooray4mo · Oct 2, 2023

I have a couple lenses that I bought 2nd hand. They both came with one of my Minoltas (one of the X series), but unfortunately didn't come with an adapter for them. I'd really like to use them, but need help identifying the mounts so I can get an adapter to attach them to my Minolta XG-1 (if that's even possible)
Can anyone tell me what kind of mount they are?
The first one is a Vivitar 28mm 1:2.5 Auto Wide-Angle lens. And the 2nd is an Auto Super-Lentar 1:3.8 f=21mm. It's probably important to note that the Super-Lentar has a pin that can slide in and out from the inside if you rotate the ridged part of the lens.

The only one you possibly could get an adapter for is that screw mount lens.

That Vivitar looks to be a Pentax K-Mount.

Not a Pentax K-mount. Those use a tab, not a pin.

The threaded lens looks like an M42.

I think you're correct. Looking at the guide that Scotty sent, the Super-Lentar looks like a Pentax M42 screw mount.

*facepalm* of course after making a post and taking the pictures of the lenses to go along with it, I find that the Vivitar lens is already set to fit onto my Minolta cameras :uncomfortableness:
