Canon's Canonet G-III QL19 — fixed f/1.9 35mm rangefinder, shutter-priority AE, CdS meter, 1972.
The Canon Canonet G-III QL19 was the 1972 final development of the QL19 within Canon's Canonet line of fixed-lens 35mm rangefinders. It shared the G-III body and features with the more sought-after G-III QL17, differing mainly in a slightly slower fixed lens, and marked the end of the Canonet rangefinder line.
This is a 35mm fixed-lens rangefinder that focuses through a coupled rangefinder rather than autofocus or zone focus, with a permanently mounted 45mm f/1.9 lens and no interchangeable mount. It uses a leaf shutter in the lens and offers shutter-priority automatic exposure alongside manual control, metered by a CdS cell. It also carries Canon's QL Quick Load film-threading system.
The G-III QL19 suits street, documentary, travel and general shooting, pairing a bright fixed lens with quiet leaf-shutter operation in a compact metal body. The shutter-priority mode makes it quick to use, while manual control and rangefinder focusing add precision. It offers much of the G-III appeal at a marginally slower lens speed than the QL17.
On the used market, check the foam light seals, which perish with age. Inspect the fixed lens for haze, fungus and separation, since it cannot be replaced. Test the coupled rangefinder patch for contrast and alignment. The CdS meter was designed around a 1.35V mercury cell, now banned, so confirm the meter works and account for voltage with a modern battery. Check the QL loading, film advance and rewind, and look for battery-door corrosion.
