K mount lens on M42 Camera

Do they make adapters to use a k mount lenses on a m42 camera or in my case a m42 tele converter? I know they make k mount to m42 adapters that allow m42 lenses on k mount bodies. I want the reverse adapter

No. The K mount has a wider diameter than the M42, so you cannot mount the lens inside the body. M42 and K mount have the same registration distance so you can mount an M42 on a K body with the right adapter. Since the K mount wont fit in a M42 body you would change the registration distance and would need optical correction to get infinity focus. This is the main reason no one has made a K to M42 adapter. You can however get optically corrected Nikon F, Canon FD, and Minolta MD adapters for K mount cameras. So who knows. Maybe the Chinese will make a K to M42 adapter some day.

Check out this thread.

Yes, PK lenses can be used on M42 cameras! So can Canon, Nikon, Leica, Sony/Minolta, Petri, Olympus, Contax/Yashica, TV and cine lenses, et al, and with only cheap non-optical adaptors! It's a miracle!

But there's a catch: without major surgery, they can only be used for macros, reversed. Bother. That's probably not what you were looking for. Sorry about that.
