Abstract
The handle grip and electronic controls of a handle control for a lens zoom speed control are ergonomically designed to provide quick comfortable access to all of the control switches. While grasping the rubberized foam handle grip in the palm of the hand of the operator, a thumb engages and holds a push button or rocker switch to switch between the wide angle and telephoto mode. Simultaneously, an inner edge of the forefinger engages and rotates a speed control dial to increase or decrease the speed of lens zoom in the selected wide angle or telephoto mode as controlled by engagement of the thumb with the appropriate mode switch. Rotation of the speed control dial away from the operator (in a counterclockwise direction), causes an increased speed of zooms whereas rotation of the dial towards the operator (in a clockwise direction) decreases the speed of zoom (in the selected wide angle or telephoto mode).
