I bought a Mamiya lens, can I use it on my Pentax film SLR?

Me, too.

I wouldn't loose the ability to use in-camera metering, right?

No idea. That's usually dependent on the body, and I'm not very conversant with Pentax dSLRs, as I'm a Canon shooter. I'd assume it'll work like the Takumar. Ah, found a page about using MF lenses on Pentax; sounds like you'll have stop-down metering no problem.

My recommendation would be to head over to the mflenses forum, or the Fred Miranda Alternative Gear area, and ask if they can ID the mount and if there are any adapters available.

Ok, I did some more googling, and I think you're SOL. There are no commercially available adapters for the Mamiya bayonet mounts. The one you've got is (I think) the NC-bayonet, because it says "CS" on it. (If it says "ES" on it, it's XTL-bayonet). I'm going by this thread on mflenses.com.

In addition, it looks like the register distance is 45.5mm (not sure about this). Which is exactly the same as the Pentax K mount. You have no distance to work with for an adapter ring, so even if you found one, you could never achieve focus to infinity with it (not necessarily a problem for portrait or macro work, but sucks for landscape).

Maybe you can sell it again on the 35mm Mamiya board.

Inkista, thanks again for your help. I've been away for a few days and I think I'll post a thread on the mflenses.com board with the mount pictures and all, and ask them about the whole thing.
I'll keep you updated.

Thanks again!

Hey Inkista, I asked about the lens on the mflenses forum and you were right, I can't use it.
The mount is one of Mamiya's post-M42 mounts, which are rare and seems not very popular. There are no adapters for it. Anyway, it doesn't matter, I got it cheap anyway. Thanks again!

You're welcome! And I'll bet you know a lot more now about used lenses you can buy for your camera!

Yeah, definitely! I saw some pretty cheap used 35mm lenses on B&H. I'm just sad because I don't have time for photography because of my work and college. But, better times will come.
