The Voigtländer & Sohn Stereophotoskop is a stereo camera produced by the long-established Braunschweig optical maker Voigtländer. It dates from the era when paired-lens stereo photography was a mainstream amateur format.

Auction data for this model is extremely thin: a single recorded UK saleroom result from 2003 hammered at £70, which gives a reference point rather than a reliable market value. Because that result is now more than two decades old and represents a wholesale hammer price rather than a retail figure, what a Stereophotoskop is worth today depends heavily on completeness, condition, and the presence of original accessories at the time of sale.
