Before its 1926 merger into Zeiss Ikon, the Berlin company C. P. Goerz sold several folding-bed plate cameras under the name Tenax[1] and Pocket Tenax, beginning around 1906. These were part of Goerz's Tenax camera family.

Plate sizes were 6.5×9 cm, 9×12, and 10×15 cm.

Goerz offered a special "Autofoc" feature, a cylindrical mechanism which advanced the lensboard to a standard focus distance automatically when the camera was opened. The "Manufoc" versions of the Tenax lacked this feature[2]. The Taro Tenax folding bed cameras were the budget line of the original Tenax series.
