The Voigtlander SuperB was the only twin-lens reflex camera from the German brand to directly compete with the Rolleiflex, a high-end model released in 1933. It is also the only true 120 mm dual-lens reflex camera flagship from the brand. Launched in 1933, it was produced in 1939, just before World War II. Stripped of all its elegance, it completely revolutionized the image we had of traditional twin-lens reflex cameras. The horizontal film advancement, the back opening system, the counting system, and other aspects of its construction, design, and operation are unique. It is equipped with a Heliar 75 mm f/3.5 viewfinder lens (5 lenses in 3 groups, for stunning images). It is also equipped with a Skopar 75 mm f/3.5 camera lens (4 lenses in 3 groups, Tessar construction). It works perfectly! The shutter speeds are accurate at all settings. There is a small scratch on the leather.
