The Goerz Stereotenax is a stereo plate camera produced by the German optics maker C.P. Goerz, designed to capture paired images for stereoscopic viewing. It dates from the early twentieth-century era of folding stereo cameras and was sold as a specialist instrument for amateur stereo photographers.

Sales data for the Stereotenax is extremely thin: a single recorded UK auction hammer result of £140 from 2005 is the only data point, so a current market range cannot be reliably stated for 2026. Buyers should treat that figure as a wholesale saleroom level rather than a retail price, and recognise that condition, completeness of the lens pair and shutter function will heavily influence what one sells for today.
