ISO Duplex Super 120 Stereo
The ISO Duplex Super 120 Stereo is an Italian-made stereo camera produced by ISO of Milan, designed to take paired stereo images on 120 roll film. It dates from the postwar era, when several European makers offered medium-format stereo cameras aimed at enthusiasts of three-dimensional photography.
At recent UK auction, hammer prices for the Duplex Super 120 Stereo have ranged from £150 to £260, with a midpoint around £210 based on the limited results on record. As of today in 2026, the model trades thinly at saleroom level, so any single sale can shift the apparent value, and condition of the twin lenses and shutter directly affects what each example sells for.
