Canon's Canonet QL17 — fixed f/1.7 35mm coupled rangefinder with leaf shutter and Quick Load, 1965.
The Canon Canonet QL17 was a 1965 addition to Canon's Canonet line of fixed-lens 35mm rangefinders and the model that introduced the QL, or Quick Load, film-loading system to the range. It sat among Canon's more capable Canonets of the mid-1960s and established the QL17 name that Canon later reused for the widely admired New and G-III versions.
This is a 35mm fixed-lens rangefinder with a coupled rangefinder for focusing rather than autofocus or zone focus. The 17 in the name refers to the f/1.7 maximum aperture of its fixed lens. It uses a leaf shutter in the lens and a coupled light meter for exposure, and the QL Quick Load mechanism simplifies threading the film. The exact focal length should be confirmed against the specific body.
The Canonet QL17 suits street, documentary, travel and general shooting, pairing a bright fixed lens with quiet leaf-shutter operation in a compact metal body. Its fast f/1.7 optic makes it usable in lower light, and the rangefinder focusing gives precise results for a fixed-lens compact of its era.
On the used market, inspect the foam light seals around the film door, which perish with age. Check the fixed f/1.7 lens for haze, fungus and separation, since it cannot be replaced. Test the coupled rangefinder patch for contrast and alignment and confirm the meter still responds; early Canonet meters were designed around mercury cell voltages, so verify the reading against a known source. Check the QL loading mechanism, film advance and rewind, and look for battery-door corrosion.
