For this reason, in the situation you describe, try AF-S, focus once before starting filming, and then start the video recording. Works great for the focusing situation you describe above plus of course no focussing noise.

I haven't tried the AF-F mode on my D4 yet, but I plan to try it soon if only to see if it has gotten any better than my D7000.
