I always manual focus when doing macro, and that does not stop the lens from turning off when i go into the menus. I don't care about autofocus, but the autofocus speed moves at the same pace as the lens turning off. Yes, the new firmware did make a difference in the autofocus speed (I'm using the X-T10, that had the new autofocus from the factory), but the lens is still turning off. And when I work at the closer distances, the lens takes quite some time to turn off, and on again, every time I want to check if I hit focus.
