The new 055 carbon fiber 4-section tripod delivers maximum rigidity from the lightest components. The 100% carbon fiber tubes and new QPL leg locking system increase the tripod’s rigidity and absorb vibrations, stabilizing camera equipment under any conditions. The key feature of the 055CXPRO4 is its 90 Degree Centre column mechanism, which allows the column to be extended vertically as normal, or horizontally. The horizontal column mechanism is housed within the tripod's top casting for compactness, but it is easily and quickly extended whenever you need it. Switching between vertical and horizontal column orientation requires no disassembly, and can even be done with a camera attached. The 4-section legs of the 055CXPRO4 tripod make it extremely compact. The legs are also fast to extend and adjust, thanks to the Quick Power Lock levers. The special design of the QPL levers allows single-handed opening of all leg sections in one action. Intuitive and ergonomic leg angle selectors allow each leg to be independently and solidly set to any of the preset angles, again allowing considerable positioning freedom. A bubble level is built in to the top of the Centre column for precise framing. The bubble level rotates freely around the Centre column, so it can be positioned wherever it's easiest for you to see.
