The E-10/20 Ball Head is part of the ET Tripod kit and provides full creative control with a separate panning and main locking knob.
The SIRUI E Series Ball Heads have advanced features that provide safety and flexibility. The SIRUI patented safety lock system, with secondary lock release on the Quick Release platform, lets you re-position your camera/lens for proper balance, without worrying that they will accidentally slide off of the platform.
The use of Arca-compatible quick release plates allows you unlimited choices and options. (Note: safety lock design not available from other brands).
SIRUI's unique locking mechanism provides unequaled locking force even with loads up to 12 kg (26.5 lb.)!
The handy Bubble Level makes horizontal alignments fast and repeatable. And for fast, precise panorama and stitching control, the degree scale on the base of the ball head is completely visible. Moving in precise increments couldn't be easier!
