The DT Ring is a rotating camera mount for DT iX cameras (iXG and iXH) allowing the camera to rotate 360º without deviating from the optical axis. This of particular interest to organizations utilizing photogrammetry to create 3D models of their collections. The fast, accurate, repeatable movements allow for rapid distortion mapping. The rotation ring includes 15º markers as well as detents for 15º and 45º for precision and repeatability. The DT Ring is compatible with the DT Advanced Leveling Head for use with a V Cradle.
