Quick Film Loading
The Canonet loads with 35 mm film for a 24 x 36 mm negative size. An advantage of this model is the quick loading of film without winding the film leader around the take-up spool. Gently pulling the film leader across the opened back to the alignment mark and closing the camera cover advances the film.
Automatic and Manual Settings
The QL17 has an autoexposure system with shutter priority. The PX625 mercury battery, no longer available in the United States, powers the autoexposure system. Canon̵7;s ̶0;Electric Eye̶1; works with the shutter speed, film speed and aperture for automatic exposure. Releasing the aperture ring from the ̶0;A̶1; positions allows manual adjustment of the aperture to any setting from f/1.7 to f/16. Canonet users can still operate the camera with manual settings that require no battery power to activate the mechanical shutter.
Lens
The Canonet produces wide-angle images with its one standard lens. The Canonet QL17 has no interchangeable lenses. The Canon SE 45 mm f/1.7 lens contains six elements in five groups. This lens features a low profile with tightly spaced rings that adjust the settings. The shutter speed adjusts as a dial on the lens. Shutter speeds range from one-quarter to 1/500 second.
Viewfinder
The QL17 features a bright-line type viewfinder with a parallax correction mark. Canonet users see an exposure indicator that warns of underexposed or overexposed images. Users also see a double image that unites as one crisp image when the focus lever adjusts the lens elements.
Available Light Photography
Film speed ranges from ISO 25 to 400, suitable for bright to low lighting conditions. The ̶0;Bulb̶1; setting allows long exposures, such as for night scenes. A cable release and tripod minimize camera shake. Changing the aperture setting from ̶0;A̶1; manually sets the aperture at any f/stop required for this exposure. The ̶0;B̶1; for ̶0;bulb̶1; setting is on the shutter speed ring and sets with the help of the bulb setting lever.
Flash Photography
Cordless flash photography is possible with the optional Canolite D flash unit. This unit powers with two 1.5 volt alkaline batteries. The Canonet includes flash synchronization with adjustable speeds up to 1/500 second. The automatic flash control circuit sets the correct aperture to the shooting distance.
