Gitzo's top-of-the-range Systematic tripods are modular, with a flat centre disk that can be interchanged for centre columns, levelling bases and other components. Because they have leg angle settings but no column as standard, Systematic tripods are all capable of near-groud level shooting. Leg tubes are in 6X carbon fibre with Gitzo's efficient G-locks. The GT5542LS is a Gitzo Series 5 tripod designed for strength and torsional rigidity under extreme loads of up to 40kg (88lb) and with lenses up to 800mm. With its 4-section legs fully extended, it reaches eye level even without using a centre column, yet it remains compact when folded.
