Canon FD lenses

Aside of being badly worded, there is no word on the origin or meaning of those F mounts.

The fact is FD has no meaning, it's just a designation to delineate that series of Canon lenses.

I've found out today what F.D. means, in an old Canon Corporation magazine advertisement from the 1980s for their new range of FD cameras it means "Full Diaphragm" which intimates the user has full diaphragm control, as opposed to their previous range of Canon FL lenses, that can only be used in the stoped down mode.

Well, then "Full Diaphragm" stands for "Open Aperture Metering" + "Shutter Priority Automatic"


And I guess "FL" is derived from "F-camera Lenses". Or got you some information on this too?

The FL Lenses came out at the same time than the FX camera. So yes, probably, "F Lenses"

As you write AgX, it looks like because the FL cameras had stopped down metering, FD signifies the camera because it had open aperture metering was named FD" full diaphragm" because it had full diaphragm control.
