How to focus the rocker arm

The cameras on the rocker arm are all wire-controlled, and there is a control part at the other end of the rocker arm, through which the focusing system can be controlled automatically or manually. Rocker arm is a kind of large-scale equipment used to shoot TV series, movies, advertisements and other large-scale film and television works. In recent years, there are also small rocker arms suitable for SLR and small cameras. Mainly when shooting, you can shoot the scene in all directions and don't let go of any corner.

Our usual camera and photographic auxiliary equipment are tripods, whose function is to fix the plane position and adjust the level, which is convenient for photographers to push, pull and shake. The rocker arm adds a lifting function to this function. Moreover, the lens is more "exaggerated" when shaking, and it can shoot a magnificent scene.
