(From company literature) Gitzo G1375M Magnesium Universal Ball Head. 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.
This model features a single "I" slot for the camera fixing screw to allow fine positioning of the camera on the head.
