Manfrotto MS050M4-Q2 is an L Bracket for Manfrotto heads using the RC2 (200PL) pattern quick release. The bracket allows a camera to be rapidly repositioned from horizontal to vertical, keeping the lens around the same axis. Note that in order to rotate around the lens axis you will need a pro size body or standard plus battery grip. Standard DSLR bodies are not tall enough and so can only adjust to the horizontal centre in both orientations. Anti-rotation locks stop the camera shifting on the bracket. Built-in bubble level to aid levelling. Bracket length in each dimension is 15cm. Max load of 15kg.
