The Canonet Junior is a 35mm viewfinder camera with programmed automatic exposure controlling the shutter and aperture. It was made in Japan by Canon and introduced in 1963. A sibling of the Canonet, this camera was conceived for compactness and operation ease. The shutter speed and aperture were set automatically, making it easy to use by anybody. The zone focusing system divided subject distances into close, medium, and far with icons. Exposure was set automatically by the EE (Electric Eye) program. The film advance used a sprocket less spool. This made the camera 10 mm less wide and 60 g lighter than the Canonet. The lens is a Canon SE 40mm/f2.8 (4 elements, 3 groups). The shutter is a Seikosha-L programmed with speeds of 1/30 to 1/250 of a second and B. The camera has X-sync flash with a PC socket and metering by a Selenium cell; EV 7-17 (100ASA). The film speed range is ISO 10 to 200 and the original price in 1963 was about $108.00 (11800 yen). The camera also has a single action frame advance, cold shoe, flash socket in the front, rewind pop-up lever plus release button, plunger socket on the top of the shutter release, and a ¼ inch 20 thread tripod socket on the bottom.
