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 new aperture linkage was designed to reduce the film advance torque and to integrate TTL light metering. After the shutter was released, the lens reverted to the maximum aperture regardless of the film advance state.

The built-in CdS exposure meter indicated the proper aperture for the selected shutter speed. A lever switched between the high (EV9 to 18) and low (EV1 to 10) metering sensitivity ranges.
