FD?

[m._michaelis]

Is there anybody who can explain me what FD stands for? Can I use Canon-FD-Objectives for a AE-1?

[david_goldfarb]

Yes, FD lenses work on the AE-1, as do Canon FL lenses and R lenses.

EF lenses do not work on Canon manual-focus cameras like the AE-1. I

have no idea what the initials stand for (R is probably "reflex"; FD

lenses have an auto diaphragm, so maybe the "D" alludes to this fact;

no idea about FL).

[john___3]

The way it was explained to me, FD stands for "full diaphragm". These

were the first lenses that allowed metering at the widest aperture of

whatever lens was attached; the lens stopped down to the metered

aperture the instant the picture was taken. Before these lenses came

along, you had to use stopped-down metering.

Don't know if FL stands for anything.

Good question, thanks for getting it out there. And thanks to

those who cleared that up.
