Cameras using 122 film

The No. 3A Folding Pocket Kodak was the model in which Kodak first introduced 122 roll film in 1903. This film, referred to as postcard size or 3A size, gave rise to a negative measuring 3.25 by 5.5 inches which could be contact printed directly onto paper backed with postcard material. Because of this, it became the ideal format for the real-photo postcard mania of the early twentieth century, a trend which reached its height in the 1910s. The film was primarily used in Kodak's large No. 3A folding cameras, such as the Autographic versions that began to use A122 film after 1914. Kodak continued to produce cameras in this format right up to 1943, when the No. 3A Kodak Series III was discontinued. As interest in postcard photography declined, so did the demand, and Kodak produced its final batch of 122 film in 1971; none has been made since, meaning that today's hobbyists who use these cameras have to cut sheet or X-ray film to the required size or use adapters to fit 120 film.
