The CB-50D Ballhead with QP-144750 Release Plate from Feisol inherits the two-locking-system design of previous Fiesol ballhead models. The dual-caliper design provides one system to lock the ballhead sphere, and a second to lock the base plate for even greater stability. This allows for the added capability of rotating the base plate while maintaining a locked sphere. The quick release system is Arca-Swiss compatible.
