Hi!
Not quite correct. The F and FA actually stop down as you turn the aperture until you reach the point when Soft Focus no longer has any affect - from then on it is like any other A lens. So you have the same capability.
Bruce I should point out that you're slightly incorrect. F variety has no A position, so *istD will work on P mode only between f/2.8 and f/5.6 inclusive. Then the exposure values do not change if you keep on clicking. You have to use the green button trick.
