Q: 8. Is the autofocus loud or will this work well for video? I have an 11-16 but you can hear the autofocus when recording video.

A: Loud of course is relative. It is not totally silent and inaudible, but you barely hear anything at all. There is a touch of a whirring sound when the autofocus is hunting in low light for something to latch onto. Otherwise the autofocus in good light is so fast and efficient, you don't notice any sound.
