The Manfrotto 808RC4 3-Way Pan/Tilt Head is the redesigned model in the three-way range of heads. The 808RC4 now also includes the Double Axis Spring System which consists of a built-in 3.3 lb spring for both the front tilt and side tilt movements. It also incorporates dual axis bubble levels to better achieve level shots. This innovative solution, borrowed from the video industry, helps to move the camera smoothly while framing the picture, as it helps to balance some of the camera weight. In addition, it absorbs the shock to bodies and lenses when reaching the end stop of the head movement.
