When you press the button on top of this camera and it unfolds smoothly and stays solid and rigid as if there where no moving parts there: you feel you have a Rols Roice in your hands. Coupled rangefinder on the viewfinder, double and blank exposure prevention, winding knob with automatic stop on the film advance, self timer... all you need. Lens is a Tessar 2.8. In this specific camera it is uncoated but this is not a weakness. Uncoated lenses are just a type of lens that, depending on the lighting conditions of your subject, can spread more or less uncontrolled light over the film. It can be not perceivable, can add some overall haze or can add an aura around brilliant objects. Sometimes it helps to pass the threshold of under exposure on an area that a coated lens would ignore. Zeiss Ikon produced Super Ikontas B (where B stands for 6x6 format) from 1935 to 1957. This model 532/16 from 1937 to 1956. Looking the table with year of production x zeiss lenses presented in   Craig Camera; , we could say that this one was specifically produced in 1938.
