Yeah, AIAF works pretty good. But you can count on it to not do what you want sometime when it really matters

I'm testing a Canon A640 right now and I went with the AIAF for a while, just to see how well it worked. It's actually really, really effective - most of the time. But I prefer using the center point as it's foolproof. It just won't let you down.
