Systematic - the choice of exacting photographers who use long lenses and heavy cameras..
Not only are Systematic Gitzos strongest and most stable tripods, theyre 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. The Easy Link attachment (3/8" thread) allows the user to attach various accessories such as a Manfrotto arm to use lighting accessories.
Series 4 (top leg diameter 37.0mm) is becoming popular thanks to the rigidity from large leg diameters, while the top casting (shared with Series 3 models) is less less bulky and therefore easier to store and carry.
GT4543LS is the 4 section long model, a size very popular for its balance between closed length and sufficient height even without a column. It replaces the GT4542LS.
