The EX Auto is a 35 mm SLR camera made by Canon in 1972. Its most characteristic feature is a rear lens-group fixed on the camera, to which any of a small selection of front groups can be attached (by a simple screw fitting).

The available lens front-groups are:

  • Standard lens: EX 50 mm f/1.8
  • Wide angle: EX 35 mm f/3.5
  • Portrait: EX 95 mm f/3.5
  • Telephoto: EX 125 mm f/3.5

The lens focusing ring was also coupled to autoflash metering. With the dedicated Speedlite D mounted on the hot shoe and the EX 50mm f/1.8 lens attached to the camera, the CAT System automatically obtained the correct flash exposure for the subject distance. Taking pictures at night became as easy as taking pictures during the day.
