Canon FX 215840 1

Canon FX. Black body.

Canon FX is a 35mm film SLR camera made by Canon and introduced in 1964.

It introduced the Canon FL lens mount, the successor to the Canon R. After the Canonflex R-series, the Canon FX was the first in a new series having an aperture linkage on a new lens mount. The model designation's "flex" (for single-lens reflex) suffix was replaced with an "F." The FX was available with either silver or black metal parts.
