Pentax 645 Medium Format SLR Film Camera With 120 Film Back

  

I've shot multiple rolls through this camera but have upgraded to another medium format. The only "quirk" I have found with this camera (and every Pentax 645) is that you must make sure all of the AA batteries are touching the contacts in proper position when you are changing them.

Otherwise, the camera may not draw power properly and therefore will not work.
