One of the most misterious Konica Prototypes is the Domirex presented in
1963 in a photo exhibition in Japan. It is single lens reflex having no
swinging mirror, instead two small mirrors at lens corners sent 20% of the
incoming light to the finder, that way, conventional leaf shutters could be
used, synchronizing electronic flash at all speeds.

The advantages are clearly felt, once it is banned the mirror vibration present in most SLRs; another one is the silence in picture taking and the continous image viewing including the flash instant, once there is no black-out. There were built two prototypes. The first one with selenium cell, the other one with CdS.
