Systematic is Gitzo"s top of the range tripod family, 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 adapter, leveling unit or other specialized center component. Now, Systematic has been refined, with significant improvements across strength, stability and rigidity; safety and security; set-up speed, ease of use and ergonomics. New construction and bonding techniques have almost doubled maximum payloads by distributing weight more efficiently to the 6X carbon fiber legs, which also feature the G-Lock system for greater power and ease of leg section locking. In addition, design details on the distinctive new triangular top casting make changing center components even faster and safer. Used with heavier cameras and lenses up to 500mm, Systematic Series 4 gives solid support and torsion rigidity. Technical Specifications: Series 4; Leg Sections 4; Maximum Height 61.61 in; Minimum Height 3.82 in; Closed Length 24.53 in; Weight 5.09 lbs.
