| | + | '''Tenax''' was a model name used by the German company [[Goerz]] at the beginning of the 20th century. |
| | + | * the [[Taro Tenax]] ([[Goerz]] 1912) |
| | + | * the [[Plate Tenax]]/Vest-pocket Tenax (Strut-folding; Goerz 1909) |
| | + | * the Stereotenax/Stereo Pocket Tenax (Goerz) |
| | + | * the [[Rollfilm Tenax]] (Goerz 1921) |

| | + | ** Manufoc-Tenax |

| + | After Goerz was absorbed in the [[Zeiss Ikon]] company, the name Tenax was re-used successively for three different camera models: |
| − | | + | * the [[Tenax II]] ([[Zeiss Ikon]] 580/27, 1938-1941) |
| − | The first one was first named '''Tenax''' in short, and became the '''Tenax II''' when the Tenax I was released. Its Zeiss Ikon code number was 580/27. Launched in 1938, it was a 24x24mm rangefinder camera with a rapid-action advance lever placed around the lens.
| + | * the [[Tenax I]] (Zeiss Ikon 570/27, 1939-1959) |
| − | | + | * the [[Tenax Automatic]] (Zeiss Ikon 1960- ) |
| − | The coupled rangefinder was integrated in the viewfinder. It included a wedge-shaped rotating lens, that was actually attached to the lens and was interchanged with it. This system was much like the one on the [[Super Ikonta]], [[Super Nettel]] or [[Nettax]].

| − | The shutter, placed behind the lens, was a ''Compur-Rapid'' leaf shutter to 1/400.
| |
| − | | |
| − | The lens was interchangeable but only very few wide angle and tele lenses were produced. The very limited range of lenses was the following:
| |
| − | * Carl Zeiss Jena 4cm f/2 ''Sonnar'' standard lens
| |
| − | * Carl Zeiss Jena 4cm f/2.8 ''Tessar'' standard lens | |
| − | * Carl Zeiss Jena 2.7cm f/4.5 ''Orthometar'' wide-angle lens
| |
| − | * Carl Zeiss Jena 7.5cm f/4 ''Sonnar'' tele lens
| |

| − | The Tenax II was certainly inspired by the [[Robot]] camera, a small 24x24mm camera with spring-driven motorized film advance, launched in 1934. The format was indeed the same, as well as the emphasis on rapid action shooting. The rangefinder Tenax II was more sophisticated, but it was not commercially as successful, and did not survive the war, unlike the Robot.

| − | | |
| − | The '''Tenax I''' was actually launched after the Tenax II. As the Tenax II, it was a 24x24mm square-format camera, with a rapid-advance lever around the lens. But it was a much simpler camera, with a completely different body, no rangefinder, a simple folding viewfinder on the top plate, and a behind the lens ''Compur'' shutter to 1/300. Most of them were equipped with a Zeiss ''Novar'' 35mm f/3.5 lens.

| − | The production began in 1939, and it was nearly halted in 1941. A limited production continued during the war. Afterwards, the Eastern Zeiss Ikon company resumed the model. It was modified during the 1950s with a fixed viewfinder integrated in the top plate. Then it was renamed '''Taxona''', after the Eastern Zeiss Ikon company lost the rights to use the traditional Zeiss Ikon names, property of the Western Zeiss Ikon company. At the same time, the ''Novar'' name became ''Novonar''.
