The Giottos MH-3300 Pro Series II Extra Large Ballhead with MH-658 Quick Release System is a "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.
In order to cut back on its weight, this head features a hollowed out heavily anodized aluminum ball. The body shell (socket) follows a slimmer and lighter structure design, yet offers increased hardness. Three separate knobs provide optimal security and convenience. In addition to the main locking knob, it also features a friction control knob, and a separate locking knob for pan control.
The attached MH-658 is a 3.4" (86mm) long 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.
