The Foba Superball (BALLA) is the absolute top-of-the-line precision professional ball head and is in use worldwide by professional photographers using everything from DSLR's to medium-format and even large-format cameras. Foba Superball, made with precision, is one of the strongest fixation device. Large locking levers make the heads very easy to handle. They lock down firmly with just a twist. User-adjustable tension allows fine-tuning the performance of the ball to suit the shooting situation, as well as to compensate for wear over the life of the ball, which sits in a Teflon collar for smooth rotation.
