Mamiyaflex Automat B

The Mamiyaflex Automat B represents Mamiya's mid-20th century entry into the competitive world of professional twin-lens reflex (TLR) cameras, positioning it as a direct competitor to Rolleiflex. Built as a robust, medium format (likely 120 film) camera featuring two lenses in a vertical configuration, it provided photographers with a waist-level finder that offered a laterally reversed image, ideal for portrait and studio work. A key innovation was the inclusion of an automatic film stop mechanism, advancing the film to the next exposure frame upon completing the winding lever action, a feature enhancing workflow efficiency for professionals and serious enthusiasts. Mamiya's reputation for meticulous engineering and solid construction is evident in the Automat B, which utilized quality materials and precise mechanics to deliver reliable performance, reflecting Japanese manufacturing prowess during the post-war boom era. This model contributed significantly to Mamiya's establishment as a credible force in the medium format market alongside established European brands.
