Arca Swiss have launched the Z1g+ monoball tripod head, which updates the Z1g.
The Z1g+ is lighter and tighter fitting than its predecessor, and features newly engineered Motion Related Gravity Control (MRGC), which is a variable and bi directional drag that is independently operative on both axes and stabilised in all directions. With horizontal movement, the resulting friction remains constant, whereas with vertical movements, the friction increases progressively.
The Z1g+ gives a strong hold whilst also allowing smooth and accurate positioning of the camera. It also features a panorama rotation above the ball, allowing for easy panning however the tripod is placed. It weighs 960g and is 30% smaller and lighter than the Z1g.
The Z1g+ is available for $749.
