The Manfrotto Nitrotech N8 Video Head & 546B Pro Tripod kit features an innovative counterbalance system based on a nitrogen piston mechanism. Unlike heads where the counterbalance clicks into place at set levels, the Nitrotech N8 can be precisely adjusted to the weight of your camera rig. With a maximum payload capacity of 17.6 pounds, the N8 is suitable for use with a variety of video cameras. Head features include a sliding camera plate with safety lock, fluid-drag pan and tilt functions, and an illuminated bubble level. This 75mm flat-base head can be used with the included half-ball adapter for maximum flexibility in mounting to the tripod, or to a slider, hi-hat, or other support.
