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'' 3.5cm f/3.5 lens. It also existed with a Carl Zeiss Jena 3.5cm f/2.8 ''Tessar''; in limited numbers.

The '''Tenax I''' (code no 570/27) was actually launched after the [[Tenax II]]. Like the Tenax II, it is a 24×24mm square-format camera using [[35mm film]], with a rapid-advance lever around the lens. But it is a much simpler camera, with a completely different body, no [[rangefinder (device)|rangefinder]], a simple folding viewfinder on the top plate, and a behind-the-lens ''[[Compur]]'' shutter to 1/300.Tenax I (and Tenax II) was constructed by Hubert Nerwin. Most of them are equipped with a Zeiss Novar 3.5cm f/3.5 lens. A smaller number have a Carl Zeiss Jena 3.5cm f/2.8 [[Tessar]].

After the war, the Eastern Zeiss Ikon company continued the model. At the beginning the shutter was a ''Compur'' to 1/300 or a ''Compur-Rapid'' to 1/500, then it became the East German ''Tempor'' to 1/300. The lens could be the same Zeiss ''Novar'' 35mm f/3.5, or a Carl Zeiss Jena 37.5mm f/3.5 ''Tessar''. The body code number was 111/23 with the Novar and 111/24 with the Tessar.

The Tenax was modified in 1953 with a fixed viewfinder integrated in a higher top plate with the exposure counter inside it, and a revised advance lever. Soon after it was renamed '''Taxona''', because the Eastern Zeiss Ikon company had 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''. The tip of the advance lever became black in 1954. The production ended in 1959.

After the war, the East German [[Zeiss Ikon]] company <!-- Was it really "Zeiss Ikon"? I thought it was "Carl Zeiss". Carl Zeiss Jena was the lens maker. This is the part of the Zeiss Ikon camera company that remained in East Germany, mostly in Dresden. [http://www.praktica-collector.de/Pentacon.htm This page] tells me that it became VEB Mechanik Zeiss Ikon in 1953 and VEB Zeiss Ikon in 1955. --> continued the model. At the beginning the shutter was a ''Compur'' to 1/300 or a [[Compur-Rapid]] to 1/500, then it became the East German Tempor to 1/300. The lens could be the same Zeiss Novar 35mm f/3.5, or a Carl Zeiss Jena 37.5mm f/3.5 Tessar. The body code number <!-- What does this mean? Is it inscribed somewhere on the camera? Or what other significance does it have? It is the catalogue number, that is often used to identify Zeiss Ikon products. --> was now 111/23 with the Novar and 111/24 with the Tessar.

Tenax I (the tip of the advance lever is missing from this camera)

The Tenax I (code no 570/27) was actually launched after the Tenax II. Like the Tenax II, it is a 24×24mm square-format camera using 35mm film, with a rapid-advance lever around the lens. But it is 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.Tenax I (and Tenax II) was constructed by Hubert Nerwin. Most of them are equipped with a Zeiss Novar 3.5cm f/3.5 lens. A smaller number have a Carl Zeiss Jena 3.5cm f/2.8 Tessar.

Production began in 1939, and it was nearly halted in 1941. There was limited production during the rest of the war.

After the war, the East German Zeiss Ikon company continued the model. At the beginning the shutter was a Compur to 1/300 or a Compur-Rapid to 1/500, then it became the East German Tempor to 1/300. The lens could be the same Zeiss Novar 35mm f/3.5, or a Carl Zeiss Jena 37.5mm f/3.5 Tessar. The body code number was now 111/23 with the Novar and 111/24 with the Tessar.

The Tenax was modified in 1953 with a fixed viewfinder integrated in a higher top plate with the exposure counter inside it, and a revised advance lever. Soon after it was renamed Taxona, because the East German company had 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. The tip of the advance lever became black in 1954. Production ended in 1959.
