(From company literature) Gitzo G1276M Magnesium Universal Ball Head with Quick Release. Same as the G1275M except with a quick-release plate. Gitzo Off-Set Ball heads are renowned for smooth operation and positive locking. The rotating center socket is unique to Gitzo and provides a range of movement impossible with conventional heads. The graduated base, with its independent lock, allows perfect panoramic positioning.
This magnesium head is 20% lighter than the aluminum version, and a significant saving for photographers on the move. A new Teflon-based anodizing process gives the ball a refined, even smoother movement.
