Manfrotto 502HD Pro Video Head with 75mm Half-Ball allows full smoothness control while shooting thanks to the variable fluid mechanisms. Ideal for latest camcorder and HDSLR cameras supplied with external accessories (4kg max capacity with Ø75mm half ball connection). Manfrotto's patented bridging technology (inherited from the 509HD and 504HD heads), the 502HD is designed for executing cinematic moves with compact camcorders and DSLR video cameras. It supports up to 4Kgs, and spring-loaded counterbalance is set for that weight. 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 of course independent locks for pan and tilt, and drag for both is selectable in a continuous range from zero to the max level. This allows you to operate the head in a confident, smooth manner using the included pan bar. Pan drag and tilt drag are continuously adjustable from 0 (no drag) to the maximum level 75mm half ball connects to the corresponding bowl in a tripod (not included) and enables precise leveling Sliding quick-release plate secured by secondary safety system
