MANUAL FOCUS on MAVIC

From the DJI Mavic FAQ page, it appears there is a manual focus mode (not tap-to-focus) with a focusing slide bar, but I haven't seen any mention of it in reviews or from people who have received their drones. Does anyone know if this is actually a working feature on the Mavics being shipped?  If you've used it, what's your experience with it?

FAQ QUOTE:
"2. When shooting in manual focus mode, my shots are blurred even when moving the slider all the way to infinite focus. Why?
The focus range of the Mavic is 0.5m to infinite. Slide along the bar until you reach a focus point. Sliding straight to infinite focus does not guarantee sharp focus."

I have it and it is a pain. You are alaways having to refocus manually and I want to lknow if there is any way to get it off.

Any ideas on how to get rid of it
