Canon FX

Jump to: navigation, search

The Canon FX is an SLR camera that uses 35mm film and was introduced by Canon in 1964. It superseded the more elaborate Canonflex series and introduced the new Canon FL mount for its interchangeable lenses. The built-in meter uses a CdS cell that is powered by a mercury battery. The meter can be set from ASA 10 to 800, and has a range of EV 1 to 18 (ASA 100). Shutter and ASA are coupled to the meter, with a needle visible on the top deck showing the proper f/stop to manually transfer to the aperture ring

A meter-less variation of the camera was also available called the Canon FP. There is also a dual-branded Bell & Howell / Canon FX.

It uses a cloth focal plane shutter with speeds from 1s to 1/1000 with B. It supports electronic flash sync with a PC connector on the front of the camera. A self-timer is also available. The finder has a split-image rangefinder at center, surrounded by a fresnel matte screen.

The FL lenses introduced in 1964 alongside this model lack an "A/M" aperture control near the breech lock ring.[1] The depth of field for any aperture selected on the silver f/stop scale may be previewed by twisting the white dot on the black ring behind the aperture scale to the left.[2]

The stubby lever above the PC terminal is a mirror lockup, specifically for Canon's FL 19mm f/3.5 wideangle (first version).[3]
