Ringing "vorprogramiert".

My experience at a tolerable problem of "ringing":
The ringing is at all tripods without spreader or otherwise stabilize the three legs is a problem. The best remedy is to hang the camera bag / camera backpack on the hook under the center column. Thus, the tripod legs are biased and stopped ringing effectively. I press the tripod aware something down, hang a backpack and have a stable base with a higher extract. At ground level the tripod is quite stable. My 2,2m Studio tripod or my big Nivelierstativ wooden I need not "bias", but since these are statbil / equipped with a mid-level spreader also sauschwer.
Otherwise, this is a professional well-made tripod and can compete with the professionals from Gitzo, Sirui, Triopo, Cullmann ... easily. Four stars? Yes, the center column in the horizontal can not by design "super resistant" are arritiert. Again helps counterbalance.
