The UBH 45XC Ball Head with X-Cross Clamp from UniqBall is a lightweight, Arca-type compatible ball head which also functions as a pan-and-tilt, gimbal, or video fluid head. The head has a built-in leveling base, and within the base is a separate ball with its own movement. The leveling base levels the horizon, and under the quick release is a lock for the second ball to release the lock and tension at the same time. Therefore, it can move like a gimbal head, or pan smoothly like a video fluid head. Releasing the lock completely allows for a pan-and-tilt head movement.
The bidirectional X-cross clamp has more than one entrance point, enabling lens plates or macro focusing rails to enter straight, and camera plates to enter from the side without moving the clamp. The 1.6 lb ball head, which can hold large telephoto lenses, has a load capacity of 90 lb.
