A boom is indispensable for recording with the camera positioned outside the centre of the tripod. Especially for top down, macro, food or reprophotography, the boom is unavoidable. It’s also perfect as a Mini Video Jib.

What sets the SIRUI HA-77 apart is its telescopic function. The arm can be extended to 77cm, making it extremely flexible. With 90º rotation and 90º tilt to any side, almost any position can be obtained. Thanks to the grippy foam rubber, the boom can be safely operated.

You will be surprised at the functions that this compact all-rounder offers and how much it simplifies your life as a photographer.
