Many thanks, Matt. Great tip. I, too, have the 67 300/4, and I'm looking forward to using it on my 645z when I purchase it.

Many thanks, Douglas. I'll definitely check out eBay. I don't mind everything being manual, at all. That's one of the reasons I'm still using my trusty old Pentax 67 cameras. I'd keep using them, but traveling with film is getting more and more complicated. My thinking is that I can use the 645z as my primary camera, and use a K1 as a backup.

I have been using a Pentax 67 camera for years, and, now, I'm thinking of changing to the digital Pentax 645z. I have several 67 format lenses, and I would like to use these with the 645. If you mount a Pentax 67 lens on a Pentax 645z camera using the appropriate adapter, when you look into the camera's viewfinder, do you see a full rectangle, or is there a circular crop in the center? Any advice would be welcome. Many thanks, John P.S. Also, I would like to use my Pentax 67 lenses on the Pentax K1 camera. When I asked about this at the Pentax booth at last fall's PhotoExpo in NYC, I was told that there is no adapter for this. I can't imagine that this is true. Does anyone know the answer?
