Legs which provide a working height from 3.9 to 61 (10 cm to 155 cm)--3- or 4-section carbon fiber and 3- or 4-section aluminum--are available separately. Four legs provide increased stability and support for your camera and additional support accessories like suction mounts clamps and spikes are available separately.
