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 Arca Swiss Monoball Z1 Ballhead eliminates the need to modulate the tension, because its elliptical nature corrects it by virtue of its own design. The load stays exactly where you tell it to once locked into position. A separate control is set to apply a constant minimum friction, which allows the photographer the peace of mind that comes with knowing that his gear will never move of its own volition. The heavier the equipment, the more the advantages of the Arca Swiss become evident. The exquisite finish adds to the exact positioning capacity.
This Z1g (giant) Monoball version is a large single axis ballhead with panning capabilities, and will support the heaviest of cameras. The ballhead includes the “Arca” style quick release system for quick mounting and dismounting of cameras.
Tension adjustment thumb-dial built into the indexed friction control knob
PMF design offers progressive vertical axis friction control
