Gitzo\'s 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. In Gitzo\'s Series 3 - a particularly flexible and adaptable size ideal for use with lenses up to 400mm and under loads of up to 25kg - the GT3542LS is 4-section tripod that reaches eye level when fully open, yet folds to a relatively compact closed size.
