The E-20 Ball Head with TY-50E Plate from Sirui is a 12.7 oz aluminum camera support that features an Arca-type compatible quick release system. The head has two separate knobs, the larger knob unlocks to release the ball movement, and the independent pan lock releases the 360° panning base, which has 5° scale markings.
The weight capacity of the ball head is 26.5 lb, which makes it suitable to support large DSLR and medium format cameras. Furthermore, inside the clamp there is a safety stop and on the side of the clamp a security pin release button, which prevents the plate from accidentally sliding and falling out. The included TY-50E plate has a machined eyelet for a hand or shoulder strap.
