Using Pentax 67 lenses on Pentax 645z Camera

  1. 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,


    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?

    There are adapters for both 67 to K and 67 to 645. When I still had it I rarely used 67 lenses on K3 and KIIs. I's kind of the case of the tail wagging the dog though. Everything is manual, of course.There is a Pentax version and generics for the 67 to K. Check out on ebay, lots of options.
  3. 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.
  4. 67 lenses work great on 645 gear. I use a 67 300/4 on my 645D regularly with no problems. I did hear of another user who had problems with internal reflections caused by a shiny surface on the inside of the adapter. So when I bought mine I got a little flat black model paint pen and used that to black out all the inner reflective surfaces, just in case.
  5. 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.
