Argus C9

Kodak got into the market with the Retina I in 1934, which introduced the 135 cartridges used in all modern 35 mm cameras. Although the Retina was comparatively inexpensive, 35 mm cameras were still out of reach for most people, and roll film remained the format of choice for mass-market cameras. This changed in 1936 with the introduction of the inexpensive Argus A and to an even greater extent in 1939 with the arrival of the immensely popular Argus C3. Although the cheapest cameras still used roll film, 35 mm film had come to dominate the market by the time the C3 was discontinued in 1966.
