Canon QL17 G-III Chrome with 40mm f1.7

The Canonet G-III QL17 is a coupled-rangefinder, leaf-shuttered, fixed-focal-length 35 mm camera first manufactured by Canon in 1972. It features fully shutter-priority automatic exposure and fully manual shooting modes. The G-III features a 40 mm f/1.7 with six elements in four groups. The exposure meter uses a PX625 mercury battery, which is now discontinued. Use a 1.4-volt hearing aid battery or a zinc-air replacement battery can also be used.
