Medium Format Cameras:

Zeiss Ikon Ikoflex
by Karen Nakamura


Overview and Personal Comments

The Zeiss Ikon Ikoflex is a twin-lens reflex camera made by the Zeiss Ikon conglomerate in the years immediately preceding and after WWII. The model I have is the Ikoflex II according McKeowns and has the Zeiss-Opton T coated Tessar 75mm / f3.5 taking lens.

Interesting quirks

Even though the lens is cocked separately from the film winding, the camera has double exposure prevention! This most probably has relegated a lot of units to the "broken" bin since people didn't realize that you have to wind the film before cocking the shutter. Also, if the film counter has counted past '12' then you have to reset it back to '1' before it lets you shoot again as well. Those darn Zeiss engineers, they were too smart for their own good. There are actually four shutter interlocks:

Looking at the web at other people's cameras, McKeowns has a couple of mistakes in his 2001-2002 edition. First he doesn't think the II came with both a Tessar and a Prontor (1-300) shutter in the same unit, he thinks that the Tessars only came with Compur (1 - 1/500) shutters. Also his photos are a bit odd. I hope he fixes this in the next edition.

About Zeiss Ikon

Zeiss Ikon was formed in 1926 out of the merger of five companies: Carl Zeiss/Jena A.G., ICA A.G., Erneman A.G., Goerz A.G, and Contessa-Nettel A.G.

Zeiss-Ikon was a huge corporation with offices in five cities in Germany and it offered a huge variety of cameras. Unfortunately, that was also its downfall. Various divisions competed against each other horribly and there was much, much reduplication of effort. It never really took advantage of its size.

Carl Zeiss, the main company, can actually trace its roots to 1846, to the very dawn of photography and is renowned for such designs as the Tessar and T* coating. Even now, Carl Zeiss lenses grace the very best cameras from Contax to Hasselblad.

In 1972, Zeiss formed into a partnership with Yashica Corporation of Japan. Zeiss now only does lens design and makes a small amount of photographic lenses. Yashica manufactures the Contax series of Zeiss cameras.
