All Rolleiflex Automat series was produced between 1937-1956. Automat name stands to introduced automatic film counter in 1937; this counter senses the thickness of the film backing to accurately begin counting frames, obviating the need for the ruby window that forced the photographer to read the frame number off the back of the film itself. Rolleiflex TLR film cameras were most famous and the standard of news and studio photographers for decades. Many photographers still shoot with Rolleiflex TLR film cameras and black-and-white film.
