The FA (like the F4) DOES matrix meter true AI lenses if they have the maximum aperture lug. I don't know whether all do. AI'd and non-Nikon AI lenses do not have this lug (look at the back of the lens: the maximum aperture lug is the stubby protrusion at about 7 o'clock). Matrix metering requires that the camera know the actual f/ratio of the lens so it can estimate the brightness of the scene. All AF Nikons except F4 obtain the maximum aperture electronically only.
