Arca-Swiss d4 Tripod Head with a FlipLock Lever Quick Release (Geared)

Arca-Swiss D4 Overview Tilt and pivot your camera in three-dimensional space with the Arca-Swiss d4 Tripod Head with a FlipLock Lever Quick Release, which combines the advantages of a spherical head and a 3D tilt head in one compact system. Small at only 4.3" high and 1.8 lb, yet comprising a 75 lb leverage weight capacity (which accounts for the added stress of a heavy lens) and unobtrusive yet functional controls, the d4 can be used on a tripod like a normal spherical head. When both X- and Y-axes are open, one can move the camera freely. But, in contrast to a spherical head, X- and Y-axis movements can also be made separately, one at a time. And, if one of these axes is fixed, movements can be performed with even more precision.The design of this head puts the center of rotation of X and Y- tilts in the same place, making the pivoting radius of these movements very small, thus allowing users to maintain perspectives during readjustment. Also, a self-locking shock absorption feature
