Excerpt: The Manfrotto 055CXPRO3 is a large but light professional tripod designed for general-purpose use. It's one of the tallest and strongest models in the range, but surprisingly light thanks to its carbon fiber construction.
Summary: ePHOTOzine use the 055x ProB as the studio standard so I've had a lot of use from it to compare. In use, it's the same tripod with the leg levers being just as difficult to use. The legs of the older model have loosened over time and the legs will now drop on their own.
