The Goerz Roll Tenax is a German-made roll-film camera from the early 20th century, produced by C.P. Goerz of Berlin before the firm's 1926 merger into Zeiss Ikon. It was a folding strut-and-bellows camera aimed at amateur photographers using roll film rather than glass plates.

Sales data for the Roll Tenax is extremely thin: a single UK auction hammer result in March 2023 saw an example sell for £19, so as of today that figure is the only documented saleroom benchmark for what one is worth. With only one data point, it is not possible to cite a meaningful range or median, and the price a Roll Tenax sells for at auction will hinge heavily on cosmetic condition, bellows integrity and whether the original lens and shutter are intact.
