The Arca Swiss Monoball Z1 dp (Double 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 new series can withstand an incredible 60 kg (122 lbs) off-axis. Z-Series heads are available as Version Z SP (single pan) and Version Z DP (double pan). The monoball Z DP with its second panning mechanism below the camera mount keeps the camera perfectly vertical to the swinging plane, for perfect panoramic stitching of multiple images.
Special Notice for Purchases Made Before 6/15/2008
ARCA-SWISS, manufacturer of Monoball Z series, has learned only recently through representatives of the Wimberley "Sidekick" that there might be a very limited number of Monoball Z tripod heads, manufactured before June 15th 2008 with an assembly error. This assembly error has presently touched only 0.2% of all ball heads sold worldwide.
Concerns are not correct that the quickset device, which is located on the ball, turns freely and the equipment can drop immediately. When the stem loosens from the ball, a considerable force is still required to separate the two pieces.
The increased holding power of the ARCA-SWISS Monoball heads is the reason this problem has shown up, which made the assembly error visible. In each manufacturing process an individual error can have consequences, this is why ARCA-SWISS has implemented additional control mechanisms to resolve such incidents and rule them out.
The customers of an ARCA-SWISS Monoball Z1 enjoy a 5-year warranty and can ship them either to ARCA-SWISS Int. / France or to Precision Camera Works in the USA for a free inspection if they feel their Monoball is unsafe.
