No camera closes the lens down on focusing automatically. It only closes it down when firing. If it did you would see a dimmed picture in the viewfinder while it was focusing.

Yes, correct.

But - if you have a lens that have a focus shift at full aperture, then it would be an improvement to stop down 1 or 2 stops when focussing. The images would be sharper then.
