The CF 100 ENG HD 2CF two stage, heavy-duty tripod, provides maximum stability and carrying capacity. Constructed and drawn out of one-piece carbon fiber material, makes it twist resistant and lighter than dural aluminum. It features a 100mm / 4" bowl, tube diameter of 24mm (0.94") for extra stability, and is fitted with the Sachtler quick clamping system, so you can securely - and visibly - lock the tripod.
