NEX7n to be announced

It's the "or action" that causes me the most frustration with my NEX. And, by "action" I am talking about simple things like regular house lighting and trying to shoot people who are seated but may not be holding still (slight bobbing of the head, for example) or who pose for a second, but not quite long enough for the focus to lock in. This happens too often to me where I'll get a head starting to look down at a computer screen or phone or whatever even though it was looking up when I tried to lock in focus. I don't even care about sports or wildlife tracking AF speeds . . . I just want faster initial locking on speed.
