The SLIK AF-1100 E Trigger Release Ball head is considered by SLIK to be the &duo; Digital Little Brother of the enormously successful AF- 2100, the original trigger-action ball head that sparked a revolution in ball head design 20 years ago. The AF 2100 still remains a best-seller to this day. The SLIK AF-1100 E uses a patented design that allows the trigger handle to release tension on the ball when it is squeezed and lock the ball head in any position by simply releasing the trigger handle. This innovative action allows the camera to be pointed in almost any direction with ease, making a tripod-mounted camera feel like more of an extension of the body. A top-mounted bubble level makes leveling the camera quick and easy. The AF 1100 E is more compact and light-weight than its AF-2100 predecessor, making it a perfect fit for today s high-end digital point and shoot cameras, light weight DSLRs and Mirrorless interchangeable lens cameras (ILCs). An easy to use all-metal quick release system makes mounting the camera fast and simple with an easy-to-use rectangular plate that sits in a shoe that can rotate 360 Degree and lock facing in any direction. The all metal quick release plate is used in several tripod heads from Silk. MAX. OPERATING HEIGHT 5 INWEIGHT 1. 2 LBSMAX. LOAD 6. 4 LBSPLATFORM 52TRIPOD MOUNT THREAD U3/8 AND U1/4-20
