Solution to the problem with the ball head I had the tripod almost on the way back to Amazon and then I found the solution to the problem with the ball head - fix it can be "relatively easy": Opposite the wing-locking screw for the spherical head is located on the head a small, almost not to be recognized or Allen screw grub screw. This looks more like a small hole. Provided one has such a small Allen wrench, can by tightening this screw, are very tight with the thumbscrew of the ball head and used according to directions. The stand has been described in other reviews in all facets of its operational capability. I think it is doing now for your money with our system camera a good service. The deduction of points there, because the HAMA mentioned with the little Inbusschräubchen anywhere, let alone a small Allen wrench accompanied (is yes at IKEA also.).
