The Arca Swiss Monoball Z1 dp with Flip-Lock Quick Release builds on the success and popularity of their B-series ball heads. Z-Series ball heads 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. Separate purchase of an Arca or Arca-type camera plate is required for use.
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 "dp" version, which features double panning. This means that besides for the standard pan base at the bottom of the head you also get a second panning mechanism below the camera mount. It can keep the camera perfectly vertical to the swinging plane, and is ideal for perfect panoramic stitching.
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 ball heads, 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.
