The innovative design of Arca-Swiss D4 head unites the pivot points of X and Y movements in the same center with separate locking devices. With the invention of the D4 pan tilt head Arca-Swiss has put an end to setting levers of 3D heads that extend in all directions and always get in the way. No more uneven swiveling out of the camera. Arca-Swiss D4 has a rotating device base on the alignment of the camera and a rotating device underneath the camera mount enabling panorama rotations while maintaining the pivot axis. The D4 combines compactness with the lightest weight ever for a 3D head.
