The Canon F-1 is a 35 mm single-lens reflexcamera produced by Canon of Japan from March 1971 until the end of 1981, at which point it had been superseded by the New F-1 launched earlier that year. The Canon FD lens mount was introduced along with the F-1, but the previous Canon FL-mount lenses and older R- series lenses were also compatible with the camera with some limitations. The Canon F-1 was marketed as a competitor to the Nikon F and Nikon F2 single lens reflex cameras by Nikon.
The F-1 was Canon's first successful professional-grade SLR system, supporting a huge variety of accessories and interchangeable parts so it could be adapted for different uses and preferences. Their earlier professional Canonflex of 1959 had failed due to a premature introduction—before professional accessories were ready.
In 1972 Canon launched a Highspeed model with a fixed pellicle mirror that allowed the user to see the subject at all times. Equipped with a motor drive, the camera was able to shoot up to 9 frames per second—the highest speed of any motor driven camera at the time.
