The 502HD video head has a flat base with a 3/8"-16 connection, with sturdy construction and featuring Manfrotto's patented bridging technology. The 502HD is designed for executing cinematic moves with compact camcorders and DSLR video cameras. Weight capacity is 12.2 lb and counterbalance supports 8.8 lb. The balance plate's 3.27" range allows you to correct for uneven payloads that might be due to matte boxes or exotic DSLR rig configurations. The bridging technology ensures that the pan friction control is intuitive and easy to set, but also protected against knocks. There are independent locks for pan and tilt, and drag for both is selectable in a continuous range from zero to the max level. A durable padded carrying bag is included.
