In order to shoot 3D images the left and right camera lens must be the same focal length. (zoom angle). When utilizing zoom lenses the, zoom and focus position of the left and right lenses must match and the servo drives must not exhibit backlash. Most 3D rigs employ special servos and controllers. Fujinon's synchronous system utilizes lenses which have precision servos that may be used in conjunction with 3D rigs or in normal 2D, productions with familiar video controllers FeaturesThe Fujinon 3D Synchronous System is quite simple to configure. Select from a wide variety of Fujinon 3D lenses, connect with the cables - 2 each of the SA-206H-1R3 or EC-212A-R80 - power the cameras and the Synchronous System automatically syncs the lenses for perfect zoom and focus control! The Focus Control is convieniently located on the HJ-303A-06A. The optional Zoom Demand plugs directly into the Synchronous Controller. |
