This 120 folder camera is a nice example of why the Zeiss Ikonta series
has become such a highly regarded and collectible camera series. Nice
lenses, attention to detail, and a high standard of quality all make
these cameras popular with both collectors and users.
See the above links for related medium format cameras and resources.
This is a BEAUTIFUL 1940's Zeiss Ikonta A (type 521) that takes 12 6X6cm exposures on 120 film. It is in collector condition. It has the faster 75mm f/3.5 Novar lens in a Prontor SV shutter (speeds 1 sec to 1/300). The shutter is synched for the standard flash synch plug, and the aperture goes to f/32 (yes, f/32!!). This camera has a shutter release on the top of the body, and double exposure prevention (must advance the film for the shutter to fire again).

You, of course, should consult that font of Zeiss arcana, THE ZEISS COMPENDIUM by Barringer and <> Small, published by Hove in '95 and available through your village camera store (tell them to order through Silver Pixel Press/Saunders).
The blue cast on the lens may or may not be coating, though some of the Novar lenses on the later Ikontas were coated. The Novar is a Zeiss Ikon, and not a Zeiss, name: it represents a lens made on contract by an outside company. Before World War II, Steinheil and Voigtlander were the largest suppliers while, after the War, Hensoldt, a Zeiss subsidiary, gradually became the main source for Novar lenses. The Novar lenses are three-element lenses of adequate, though not sterling, performance.

To adjust the rangefinder on a Super Ikonta A, one has to loosen the
screw in the center of the little knurled wheel a little. This screw
couples the the rangefinder to the lens. The one has to set the lens to
infinity and look through the rangefinder window to an object, which is
several hunderd meters away (~infinity). By turning the little knurled
wheel the two split images of the rangefinder shall be adjusted. If the
lens and the rangefinder are both set to infinity, the screw in the
middle of little knurled wheel has to be tightened to couple lens and
rangefinder again.
As far as I know this process ist the same on a Super Ikonta C. I
assume, that the screw in the middle of little knurled wheel of your
Super Ikonta C is not tightened enough. You should talk to your
repairman about that.
Have fun.

Not really. Zeiss Ikon set minimum performance standards, and bought the
cheapest lens fulfilling the standards. So, in general, the Novars are
all relatively good performers, though not up to Tessar standards.
