P645 lenses on P67

Hi Guys,

I've just purchased a Pentax 67 in excellent condition and I was just wondering if I can use my 645 lenses on this body and if so what the results are like.
I've been looking for a 645 to 67 adapter on Ebay but had no luck. Does anyone know a source for such a thing?
Thanks in advance to anyone who can help me with this information. Cheers.

While you can mount the 67 lenses on a 645 body, you can't do the contrary without adding serious vigneting and losing focus to infinity.

The image circle of the 645 lenses are not going to be large enough to cover the 6x7 frame, and the flange registration difference will preclude infinity focus.. You are out of luck on this endeavor.
