The Tessina (officially created by Arnold Siegrist) is a high-quality 35 mm camera patented by Austrian chemical engineer Dr. Rudolph Steineck in Lugano Switzerland, manufactured by Siegrist in Grenchen Switzerland.
While many subminiature cameras were inexpensive and poorly manufactured (thus giving the format a bad name), Minox, Tessina, Gami, Edixa, Rollei, Pentax and Minolta made quality cameras capable of producing fine results—even enlarged.
