The Giottos MH-1300 Pro Series II Large Ballhead with MH-657 Quick Release System is a large "socket & ball" head that is strong enough to support the heaviest of professional SLR cameras. It has been carefully designed and manufactured to precisely position the camera easily and securely.
The attached MH-657 is a clamp style quick release system that is compatible with plates that fit the Arca Swiss standard. It comes with horizontal and vertical bubble levels, and anti-twist reversible tabs on the plate to prevent slippage when using the head in a vertical position.
Good for a Large SLR with up to a 300mm 2.8 lens. Supports up to 20lbs.
