Supporting equipment weighing up to 5 kg, the Joby BallHead 5Kuses a standard 1/4-20 threaded screw to mount compatible DSLRs, mirrorless cameras, and speedlights. It features full 360° panning and 90° tilting for nearly unrestricted movement, complemented by a separate panning lock for precise adjustments along a single axis. An Arca-type compatible quick release plate is employed for quickly attaching and detaching your gear while you work.
A numbered scale at the base of the tripod head allows you to accurately repeat 360° pans and adjust your position. At only 0.144 kg and with a height of 8.38 cm, the BallHead 5K is portable and can be easily carried without weighing you down. It is designed to be paired with the GorillaPod 5K stand and works with several Joby pro-level accessories that can extend the versatility of your ball head. However, it can also be used on any standard tripod with a 1/4-20 mount.
