ISO Duplex Super 120

The ISO Duplex Super 120 is an Italian-made stereo camera that takes paired half-frame exposures on 120 roll film, producing side-by-side images for stereoscopic viewing. It was produced by Milan-based Industria Scientifica Ottica (ISO) in the early 1950s and was positioned as a medium-format stereo camera aimed at amateur 3D photographers.

At UK auction, hammer prices for the Duplex Super 120 have ranged from around £160 to £260, with a median near £210 across the recorded sales — these are wholesale saleroom results before buyer's premium. Today in 2026 the model remains a relatively thin market, and condition of the twin lenses, shutter timing and film transport strongly influences what a given example sells for.
