Canon FX
Encyclopedia
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 (EV
1–10) and high (EV 9–18) ranges (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.
The viewfinder uses a glass pentaprism and gives coverage of 90% of the frame vertically and 93% horizontally, with a 0.9× magnification (with a 50 mm standard lens).
The FX was available with either silver or black metal parts. There are only two known all-black models; one is owned by a private collector in Indiana, USA.
