The Canon FX is a 35 mm SLR manufactured by Canon Inc. of Japan and introduced in April 1964. It introduced the Canon FL lens mount, the successor to the Canon R.

The camera has a built-in lightmeter using a CdS photocell mounted on the photographer's left-hand side; unlike later cameras, it does not meter through the taking lens. A lever switched between low sensitivity for bright subjects (EV 9–18) and high sensitivity for dark subjects (EV 1-10) (at ISO 100). Film speeds supported are ISO 10 through 800.

The shutter is a horizontally-traveling focal plane shutter supporting speeds between 1/1000 and 1 second in full stop increments, selected by a dial on the top plate on the photographer's right. The X-sync speed for flash is 1/55 sec.; flash support was through a PC socket on the front of the body.
