The 055 redefines the 3-section aluminium tripod. Thanks to its size and shape, and to the materials used, the new 055 delivers an unprecedented level of stiffness. The key feature of the 055XPRO3 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 legs of the 055XPRO3 tripod 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. The top casting of the 055XPRO3 has an Easy Link connector for supporting a photo or video accessory (such as an LED light, flash, reflector, or other piece of equipment) on an extending arm or bracket, and making the tripod into a practical mobile studio.
