Arca-Swiss Monoball Z1g + Double Panning
Arca Swiss Monoballs have been at the forefront of quality and performance. Their shape (an ellipse rather than a sphere) is still what separates them from all others. With other ballheads, no matter how good the tension modulation, you invariably will need to increase the tension control as you move the load away from the center. This is because gravity has a greater effect on gear when not perfectly level.
The g in the Arca-Swiss Monoball Z1g stands for giant, suggestive of its ability to support the heaviest cameras.
