Lens Mounts?

I purchased a box of lenses and all but these 2 were K-mounts. I'd like to see if I could use the 500mm f8 Kimunor but don't know the mount, it's obviously some interchangeable system. It's in nice shape with a preset type aperture mechanism. If you follow this link, it'll show lenses from different angles: https://picasaweb.google.com/109915535894116388289/UnknownLenses?authuser=0&feat=directlink

I have no idea what this mount is either. Looks like a decent lens, good shape but completely auto everything and it does have a macro that goes to 1:1

Thanks!

The second is a Minolta/Sony A mount.

There should be a K-mount adapter for the Kimunor, good luck finding one.

Kimunor is probably a T-mount.

A T-mount would have male threads. Kimunor provided adapters for various mounts, including T-mount.

No. There is nothing for the T-ring to attach to. You would need a T-adapter for the lens first, it would be better to get the K-mount adapter for the lens...if you can find one.

Presuming the value of the lens is nil as it is . . .

Hold the lens up to a Pentax body and see how the registration calibration works out. Looks like the existing lens base/adapter might even offer some threaded adjustment play?

If the situation allows, you might simply epoxy a cannibalized PK bayonet mount onto the lens. With a pre-set lens you don't even loose any functionality. I have a Tamron 300/5.6 with an old Adaptall ring epoxied to it where I didn't even adjust the registry distance for infinity focus as I wanted it for a backyard close-up and bird/squirrel shooter and the slight offset simply shortened the minimum focus distance as if adding a very short extension ring.

(When I do that mod, I intentionally rotate the lens so it seats with the aperture index at 10- or 2-o'clock so I can see the aperture ring without interference from the flash hood.)
