Lomopedia: Canon F-1

Canon's first truly profressional-grade SLR system, the F-1 was produced by the Japanese camera maker in March 1971. Find out more about this camera in this installment of Lomopedia!

The Canon F-1 was a 35mm SLR camera made by Canon in Japan from March 1971 until a slightly updated version called the F-1n was introduced in 1976. The new Canon FD lens mount was also introduced with the F-1, but it can also accommodate Canon FL-mount lenses, but without open-aperture metering. R-series lenses could also be equipped but functions are limited. The Canon F-1 was marketed to compete with Nikon F and F2 SLR cameras.

The Canon F-1 also supported many various accessories and interchangeable parts and had one of the largest set of accessories ever produced for 35mm SLRs.
