✪Lower gravity center compared with traditonal ballheads,which lowers the whole gravity of your shooting equipment hence ensures better stability.
✪Both the screw-knob and lever-lock can be used for tightening, which also provides better compatibility of different QR plates as well as quick-locking.Two groove standards: Arca and Pitcatinny/Nato dovetail structures
