The Minolta Super A is an interchangeable lens 35mm rangefinder camera system introduced in March 1957[1]. Image format was 24x36 on 135 film. The Super A featured a brightline finder with parallax correction and a unique button-and-lever-lock bayonet lens mount. Its behind-the-lens leaf shutter is a Seikosha-MX with speeds B, 1sec to 1/400sec, and M or X flash synchronization. The Super A system included an accessory shoe-mounted coupled selenium meter with separate selenium-cell amplifier, seven interchangeable lenses with accessory shoe-mounted finders for the wide angle and telephoto lenses.

The bayonet-mount Super A lenses used the logo 'Chiyoko' before 1958, and 'Chiyoda Kogaku' from 1958 on:

  • 3.5cm f3.5 Rokkor 35mm wide angle lens, with 4 elements in 3 groups[2][3].
