From online review.......
"For many years, the Arca-Swiss B1 Ballhead was the standard by which all other ballheads were judged. The Arca-Swiss Monoball Z1 Ballhead replaces this model and delivers the same performance in a smaller size and at a lower price. There is not much to dislike about this change.
Although it weighs only 1.5 lb (680g), the Arca-Swiss Monoball Z1 Ballhead is rated to carry 122 lbs (55.3 kg) off-axis. I can't image using something that weighs this much on a ballhead, but its high strength is important. The Z1 delivers rock-solid support to any camera/lens setup I want to mount on it. "
