Zeiss Ikon's folding 6x9 rangefinder — the Super Ikonta, rotating-wedge RF, bellows, leaf shutter, 1934.
The Zeiss Ikon Super Ikonta is a family of fixed-lens folding medium-format rangefinders introduced from 1934. It was Zeiss Ikon's rangefinder-equipped folder line, distinguished from the plain Ikonta folders by a coupled rangefinder using a rotating wedge, and was made in several frame sizes including 6x9.
This is a folding medium-format rangefinder producing nominal 6x9 frames on 120 roll film. The fixed lens sits on a bellows that folds into the body, with a leaf shutter in the lens, and focusing is by coupled rangefinder using the distinctive rotating-wedge prism arm. The camera is fully mechanical with no built-in meter, so it works without a battery.
It suits landscape, portrait and travel photographers drawn to a large negative in a slim folding body, and it is a well-regarded classic folder from the pre-war era. As a vintage camera it is deliberate and manual to use, and it is also a collector item, with value varying by lens, shutter and frame-size variant.
For a used example, inspect the bellows for pinholes in a dark room with a light inside, since folders of this age commonly leak there. Check the rotating-wedge rangefinder arm moves freely and the patch aligns, and test the leaf shutter, especially the slow speeds which often stick. Inspect the fixed lens for haze, fungus and cleaning marks and check the folding struts for play.
