In the video "Scene-Building using a single camera OP" Justin got an opening shot and then locked the gimbal for manual focus and did a series of very fast pans from one angle to the next. I couldn't find any hunting for focus in the switching between  those shots, did you stand in a place where everyone was the same distance away from you so you didn't have to adjust focus or was there really fast manual focus ? if it was manual what advice to do you have regarding that ? also what lens do you prefer in a situation like that prime or variable and focal lengths ? thank you !
