Originally posted by abruzzi Another (oddball) thought. What about hacking up a lensboard to mount large format lenses to the 67 macro bellows? The minimum distance with the bellows fully compressed is 54mm plus the FFD of the 67 at around 85mm, the shortest lens you could hack on and still focus to infinity is 139mm (unless there are large format retrofocal lenses, which I've never heard of).
I’ve done that, though not with the 67. But what I have done proves the concept. I used a Pentacon Six bellows, and Kiev 60 body caps as lens boards. It works great with barrel lenses like the 139mm Bausch and Lomb Tessar I used, but not with a lens that has a very large rear cell.
I can adapt that bellows to my Canons or my 645z, but not to the 67 body. A 67 bellows could be adapted to any Pentax K or 645 camera.
You’d be limited to longer focal lengths, as you say—short large-format lenses are indeed not retrofocus.
