The Sirui PH-20 Gimbal Head is
a great solution to the problem of shooting moving subjects with a long
telephoto lens. Ball heads and 3-way heads can be cumbersome in
fast-moving situations, but the gimbal head makes your camera and heavy
lens seemingly weightless, and you can smoothly and precisely track
fast-moving subjects.
Cross-patterned, multi-layer carbon fiber in the arm and forged
aircraft aluminum alloy in the L-bracket make the PH-20 very strong--it
can hold up to 44 lb, but it weighs only 2.4 lb. Carbon fiber also
reduces vibrations and provides better tolerance for temperature
changes.
With the camera and lens perfectly balanced on the gimbal head,
there’s no need to lock any controls. You can quickly and easily move
your camera in any direction with a very light amount of force. In fact,
a correctly aligned system can be controlled with one finger.
