2010/8/13 David Sadowski <dsadowski@xxxxxxxxx>: > Did this use two rolls of film at the same time? Yes, they had the advantage to work with the well known Automat mechanics. The two Compur shutters were coupled allowing one shutter speed wheel control and one f stop wheel control outside the camera; the film transport was coupled too, this way the camera could use two 120 film rolls simultaneously to take 12 6x6 stereo pairs, most similar format stereo cameras like the Rolleidoscop could take 6 stereo pairs only because they used one 120 film roll. The focusing mechanism was also coupled via a trough shaft and knob.
