If that is the case, then in situations like that, I could take the picture after the initial movement, and take it again afterwards, just in case the scene I'm trying to capture dissapeared before the final AF adjustment.
You could, at least it's worth a try! IIRC, there's a setting for focus priority vs. release priority, and you'd want the latter so you can release the shutter before focus is confirmed.
