I'm talking about the lenses that has all-time manual focus ability like higher-end Canon and Nikon lenses. When you half-press the shutter and the lens is hunting for focus, what happens when you try to rotate the ring in this process? Does the lens ignore your override or not?
Added (1). I'm just interested in lens optics but I haven't got one to try it myself or a friend that I can borrow one.
