126 Two questions: 1. The reaction of the Secret Service agent is a bit (time) retarded, isn't it? and 2. What a lucky kekincidence someone was filming the agent just in that moment, hm?

All of them when prepared. Think of a camera and a remote shutter control. You press a remote button while the hardware is in EXACT focus and frame.
In such long focus if you were to introduce mechanical 'buttons' to activate the 'capture' your going to alter the focus and STABILITY.
