Seems that the cheaper lenses are mixed, pentax, 645/6x7, mamiya 645, and the other lenses, usually the exacta's, etc.,

search for photodiox adapters on ebay, usually about $70 has some great deals on MF lenses as well. I already have a few on order, both from pentax 6x7 & mamiya 645.

there might be adapters for the other cameras, like hassies, but hassie lenses are pretty steep in price.
