The black Manfrotto 190XPROB Aluminum Tripod builds on the success of the 3001 series and replaces the 3001PRO model. Its Q90 horizontal center column feature has been redesigned to make it even easier to flip from vertical to horizontal. By extending the column to its highest vertical position, it can be swung over to horizontal like a boom without removing the head or disassembling the column itself. The ergonomics of the leg-angle release mechanism and the quick action leg locks have also been improved.
