Concava Tessina
The Tessina was designed by Arnold Siegrist, was produced for and marketed by Dr. Rudolph
Steineck, and built by the Swiss firm Grenchen. Technically it is a twin lens reflex, although it is far from
what comes to mind when you think of twin lens reflex. It is also a subminiature camera using 35mm film
in special cassettes. And if that wasn't enough, it had a spring wind motor drive!
It was sold as the Tessina 35 and the Tessina L. Most commonly found in chrome, it was also available
in black, gold and red.There were also a number of accessories marketed for it.
