Scaled for professional equipment, medium format and DSLRs with 200mm lens up to 400mm maximum, Series 3 Aluminum tripods combines high maximum load capacity with outstanding torsional rigidity. The new models are surprisingly lighter than previous versions and offer additional stability thanks to G-lock system. All this makes them popular alternatives to series 2 tripods. All new Series 3 Aluminum tripods now feature a third leg spread to go very low to the ground and take full advantage of the Ground Level Set. They are also provided with the new Power Disc for an safer head lock and are available in 3- and 4-section models at standard and eye level heights.
