This Series 3 carbon 4-section extra long Gitzo Systematic tripod is ideal for users requiring overhead height. Systematic is the choice of professional photographers who use long lenses and heavy cameras. Not only are Systematic Gitzo' s strongest and most stable tripods, they're also modular, with a top casting element that opens and closes to allow each tripod to be configured with a flat disk, geared or sliding center column, video half-ball adaptor, leveling base or other Systematic accessories. The latest range features Carbon eXact tubes, new ultra-stable feet and the Easy Link attachment, making the Systematic even more stable, versatile, and ergonomic. An Easy Link attachment (3/8'' thread) allows the user to attach various accessories.
