Newly redesigned, the 190XPROB makes the famous Manfrotto-patented horizontal centre column feature even easier to use. Now, by extending the column to its highest vertical position, it can be swung round to horizontal without removing the head or disassembling the column itself, so switching between framing and positioning setups is more convenient than ever. The ergonomics of the leg angle release mechanism and the quick action leg locks themselves have also been greatly improved.
