If you have the ball in idle, so it is still firmly a certain friction in the joint socket. So that's part of what I would not necessarily recommend permanently on its tripod. When locking the ball with Hillfe of 2! Locking screws can it ever unwanted Shifts come. Even the panoramic head does not rotate cleanly. He grinds off and when in running his own camp - like the head also. Bad I also find the white scale on a gold background. That's even with glasses difficult to read. For Fotgrafen with the tripod should be warning way awarded only one star. Why then I forgive 4 stars? I just tinker me a macro-motor-table and have already tested other "surfaces". This part is in any case the only that could inspire a hobbyist heart. 1 full crate overnight at 45 degrees is held to adjust without the number of degrees. This is far from more than the promised maximum load of 8 kg. However, even if never occur such weights on my table, so I know about the Suitability and stability of this ball head. But the thing has a 3 star in my discretion earned. 4. The point gets it, because it, together with a full ARCA-SWISS-compatible quick release Removable brings with it. That alone would be similar in SIRUI scrape already on total price. Only Ster downside is that it was calculated to save a penny article. Namely lacking the thread adapter / reducer 1/4 in the 3/8 inch. That's too bad, if not embarrassing for a ball head, which to assert itself on the market !? tried For the ambitious photographer and will always be never a ball head of his choice, the hobbyist, however, will be pleased with the value, even if a 1/4 "thread adapter incomprehensibly is not supplied.
