Re: [Rollei] Flat glass?


To be very literal, it was not the backs that "accepted" the
flat glass.  It was the body of the camera.  The backs permitted
the pressure plate to be relieved of its pressure, which inn turn,
permitted the film to be transported without being pressed against
the glass.

The flat glass proved to be more trouble than it was worth. Dust
mainly, scratches secondarily.  there was a calculable focus shift,
but that was so little that it did not even affect focus in the
Rolleiwide at full aperture.
