As far as I can tell, it has a hard stop at infinity and does not focus past infinity. With manual focus, the focus does not change as you zoom. I can use the magnify feature to focus on a tiny section of the scene and then zoom in or out to any length and the focus remains sharp on that one point. Hope this helps!
