Manfrotto MT055CXPRO4 055 Carbon Fiber 4-Section Tripod Kit with with MHXPRO-BHQ2 XPRO Magnesium Tripod Ball Head with Two Replacement Quick Release Plates for the RC2 Rapid Connect Adapter The key feature of the 055CXPRO4 is its 90 centre column mechanism, which allows the column to be extended vertically as normal, or horizontally to open up a wide range of framing and shooting possibilities. The special design of the QPL levers allows a more comfortable single-handed opening of all leg sections in one action. 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 it while adjusting the tripod, and without it either being obscured by the mounted head and camera, or getting in the way of head or camera controls. The top casting of the 055CXPRO4 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. The XPRO Ball Head is extremely portable, lightweight and reliable thanks to its magnesium body: it weighs only 0.5 kg and can support up to 10 kg of payload.
