The Duplex 120 was a dual-lens camera for taking stereo pairs on 120 film. It was made by Industria Scientifica Ottica S.R.L. (ISO) in Italy, c.1956. It was fitted with a pair of fixed-focus ISO Iperano 25mm f6.3 lenses in shutters with six speeds from 1/10-1/200s + P. It has a small telescope-type viewfinder at the top. The exposure is controlled by two small knobs, one below left of the lenses which set the shutter speed, and one above right which sets the aperture (f6.3-f16). Below the aperture control is a PC socket for flash sync. The film runs vertically, from the spool laying horizontally at the bottom to the take up spool at the top, advanced by a knob on the side.
The Duplex Super 120 was a similar camera with focusing lenses and a six speed shutter.
