[[Canon]]'s FD mount replaced the Canon FL mount in 1971 when the company introduced the [[Canon F-1|F-1]] and [[Canon FTb|FTb]].  For the first time, Canon [[SLR]]s offered fully coupled [[open-aperture metering]]. As with the FL mount, original FD lenses are placed against the lens flange without rotation, after which the silver "[[breechlock]]" affixing ring must be rotated to secure the lens. A (mostly theoretical) advantage is that lens and mounting flange never experience any wear from rubbing, maintaining perfect [[flange focal distance]].
 +
 +
FD lenses have an automatic position on the aperture ring, at first identified by a green circle, later by a green A. Initially only the bulky Servo EE finder for the original [[Canon F-1 | F-1]] supported this, but the [[Canon EF]] soon followed. This support for letting the camera body set the aperture would prove a boon with the arrival of the sales-hit autoexposure [[Canon AE-1]].

In 1976, Canon introduced "New FD" lenses. These offered the convenience of attaching a lens with a one-handed twist (like competing [[bayonet]]-style mounts), while still retaining the same body flange used with earlier breechlock lenses. A clever design allows the inner, mating face of the lens which contains the aperture linkages to remain stationary as the entire outer barrel of the lens rotates around it. (In effect, the whole length of the lens becomes the breechlock fixing ring).

Description

Canon's FD mount replaced the Canon FL mount in 1971 when the company introduced the F-1 and FTb. For the first time, Canon SLRs offered fully coupled open-aperture metering. As with the FL mount, original FD lenses are placed against the lens flange without rotation, after which the silver "breechlock" affixing ring must be rotated to secure the lens. A (mostly theoretical) advantage is that lens and mounting flange never experience any wear from rubbing, maintaining perfect flange focal distance.

FD lenses have an automatic position on the aperture ring, at first identified by a green circle, later by a green A. Initially only the bulky Servo EE finder for the original F-1 supported this, but the Canon EF soon followed. This support for letting the camera body set the aperture would prove a boon with the arrival of the sales-hit autoexposure Canon AE-1.

In 1976, Canon introduced "New FD" lenses. These offered the convenience of attaching a lens with a one-handed twist (like competing bayonet-style mounts), while still retaining the same body flange used with earlier breechlock lenses. A clever design allows the inner, mating face of the lens which contains the aperture linkages to remain stationary as the entire outer barrel of the lens rotates around it. (In effect, the whole length of the lens becomes the breechlock fixing ring).

In 1987 the company made a forward-thinking (but painful) move to drop compatibility with the FD mount and move to fully electronic communication with new autofocus EF mount lenses ("electro focus"—no relation to the EF film SLR).[1]

Some later Sigma FD lenses incorporated a locking version of the breech mount which looked very similar (in style, colour and placement of the locking button) to the release button on New FD lenses.

Adapters

The shallow body depth of R, FL and FD mounts makes it easy to mount other manufacturers' lenses using adapters without losing the ability to focus at infinity. This made Canon FD cameras among the most versatile cameras available. An adapter for M42 lenses is particularly handy, as these typically have a switch permitting manual aperture stop down.

Conversely, the barrels of Canon FD-mount lenses needed to be longer than those for other film SLR brands. This means, e.g., that users wanting to attach manual-focus Canon glass to modern DSLRs cannot get a mount adapter which allows for infinity focus (unless it contains optics—a weak teleconverter—which may degrade sharpness). Helpfully though, this has somewhat reduced price pressure on used FD-mount lenses, which remain widely available. This may be of interest to digital mirrorless camera users (where the shallow flange distance easily allows for FD-lens adapters).
