Here are the Images of the camera that I had modified. I bought the camera after someone at a camera show had jammed it. I got it for less than the cost of the backs so It was planned as a parts camera. It sat around for a couple of years and miraculously self healed! I decided that the problem was lubrication and since it was gorgeous sent it to Arax for CLA and modification. I then decided to have it modified to breach mount so I could use all my Pentacon mount lenses as well as the Soviet lenses.
It want with one of my 3M-3b mirror lenses which had the rear optics go cloudy for repair.
I have not been happier with any of my Saluit/Kiev6? cameras it is every bit as good as a Hassy. I can not say too much good about Georg and Arax work! Every lens fits, all of the Pentacon mount and Kiev b mount!
