Re : FA meter modes

Hi Mike,

The FA DOES NOT matrix meter with AI lenses. It would only matrix meter with
AIS lenses. The FA can only centre weight meter AI and non AI lenses. These
limitations are stated in the FA user manual. I don't know why Nikon did
this, and no one so far can explain it to me.

There is a small button on the FA to change from matrix metering to centre
weighted metering, but I often found it to make no difference at all. 

Happy shooting,

Sover

The FA also provides matrix metering with non-CPU lenses, but only
with AI-S lenses, not AI or AI modified.

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.
