The Arca Swiss Monoball Z1 sp (Single Pan) Ballhead builds on the success and popularity of their B-series ballheads. Z-Series ballheads are just as elegant, and even more perfect. The size and weight of the ball heads have been significantly reduced. The ball and fastening are now assembled using a patented bayonet mount. Various accessories can thus be quickly mounted to adapt the tripod as required.
In addition to the proven, patented Arca-Swiss features, including aspherical ball heads, axial clamping and PMF (progressive motion related friction control), the Z-series also boasts new technical developments and optimized materials and coatings. The Z series can withstand an incredible 130 lb (59 kg) off-axis.
This model is the “sp” version, which features a single panning base. The Z1 head is also available as the “dp” version, with a double panning design.
Ever since their introduction over forty years ago, the Arca Swiss Monoballs have been at the forefront of quality and performance. Today, their unique 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 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 it’s 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 Flip-Lock quick release system offers double safety locking features, with instant flip-lock release of the clamp, for quick mounting and dismounting of cameras.
A tension adjustment thumb-dial is built into the indexed friction control knob.
In the quick-locking mechanism Classic, the camera plate is clamped with a locking screw.
dp (=double panorama) means that, in addition to the first panorama swivel unit, one also has a second panorama swivel unit, located between the aspherical ball and the quick-lock plate. The second panorama swivel unit is indispensable when shooting perfect panorama pictures. The plane of the fast locking mechanism can be brought into the water along with the ball head,allowing the camera to swing in exact parallel to the horizon.
