SLIK's exclusive A.M.T. super aluminum-magnesium-titanium alloy legs make the PRO 580 DX tripod rock steady, yet lighter than it looks. The A.M.T. alloy has a 40% greater strength to weight ratio than standard aluminum, making it lighter and stronger than the standard metal used in most tripods. The PRO 580 DX is capable of supporting the weight of professional digital cameras and heavy telephoto lenses up to a 300mm f/2.8. This complete tripod offers advanced amateurs and student photographers the strength and stability they need, while its size and the use of A.M.T. alloy make it lighter and more portable. The PRO 580 DX black tripod makes setting up easy with secure, speed-release leg locks, gearless center column and 3-position, adjustable angle leg locks allow easy set-up on uneven ground or steps. The PRO 580 DX center column is actually two threaded pieces that unscrew to convert the top piece to a short column. This combined with the adjustable leg angle locks allows the tripod to be lowered to just 15 inches for very low angle or macro photography in the field.
