The flexible whip by Walimex Pro allows, e.g., a camera assistant to operate the follow focus system from a longer distance. Due to the ergonomically knurled plastic thumb knob, operating it is particularly comfortable. The connecting adapter contains a little steel ball, which allows you to adjust the footing in the follow focus system. You can lift or lower the steel ball with an Allen key. The flexible whip fits all follow focus systems with a 12x12mm socket, such as the follow focus systems by Walimex Pro.
