Use a video tripod head to balance a heavy telephoto lens with the Benro LS400 Telephoto Lens Support. Video tripod heads provide a larger base of support than photo heads, reducing vibration and instability factors at extreme focal lengths. The LS400 is sized for telephoto lenses ranging from 600-800mm and the plate is designed for mounting on Benro S6, S7, S8, and BV Video Heads. The lens support plate is vertically adjustable to support different lenses.
