This kit consists of a GH3780QR Series 3 Quick Release Center Ball Head and GT3531 Series 3 Carbon 6X Tripod. The magnesium center ball heads are renowned for their smooth and precise movements and high quality manufacturing. PTFE is applied to the ball and blocking pads to eliminate all traces of jarring and skipping. The result is highly accurate positioning adjustments, even with long tele lenses. A built in quick release system makes for quick and secure set up. The tripod features 6X carbon fiber tube, made of a unique structure of 6 crossed layers that maximizes rigidity, vibration absorption and lightweight performance. 6X tube has a high density structure made of top quality ultra-thin carbon fibers (7?m or 0.007 mm). Built-in Anti Leg Rotation makes for quick and easy set up.
