In my experience, F lenses are more solidly built than FA ones. The FA are lighter in weight and seem to have flimsy plastic barrels.
The FA are supposed to have MTF information embedded in them which is used in program mode, but I never noticed this. If it is in there, why do my FA lenses go to f/13 at a 1/750th shutter speed in bright light on my MZ-5n? The camera ought to go to 1/2000th shutter speed before it goes past f/8.
