The folding Contessa is basically an Ikonta 35 with an upgraded lens and a rangefinder, right?
The
folding Contessa is similar though not identical. Its body is a bit thicker, and it always has a Tessar while the Ikonta might have a Novar, Xenar or Tessar.
The Contessa also has a coupled rangefinder and uncoupled selenium meter and unified viewinder/rangefinder.
There were three models:
Ikonta, Contina and Contessa. Later, these became Contina, Contina II and Contessa -- the first and second models were renamed.
The
Contina II was fitted with either a Novar or Tessar and uncoupled rangefinder but no meter. With the Contina II, you focus in one window, read the distance from the dial and then set the lens to that distance. Then you compose your shot in another window. Takes some time, but it's simpler in the real world than it sounds here.
All three were created by Zeiss Ikon's Hubert Nerwin, a brilliant camera designer. They reflect Nerwin's minimalist principle that simpler is better.
There are small differences in the Ikonta, Contina and Contessa, and the Ikonta had at least three variations in its body. The quality of construction and choice of materials of all three cameras was excellent. And with the Contessa, you usually can
revive the selenium meter.
