Designed for the largest telephoto lenses, this head can tilt a 180 degrees. The giant knurled tilt-lock knob is easy to grip and operate, even while wearing gloves. The internal mechanism will auto-align as you tighten to ensure a perfect alignment with the main tilt axis of the head below. In addition to the standard 3/8"-16 threaded socket, the base of the head features a RRS-compatible dovetail to add versatility in mounting.
