GT3542L is a long 4-section, Series 3 tripod designed to reach eye-level when fully extended. The G3542L is recommended for professional cameras with 300mm lenses (up to a maximum of 400mm). Thanks both to their new design and to the use of Carbon eXact tubes, Series 3 Mountaineer tripods are lighter in weight yet more rigid than their predecessors. Top leg section diameter: 32.9mm
