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 Features The 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 HJ-303A-08A offers the flexibility of using existing standard Fujinon zoom and focus controls This unit additionally has a multitude of ports for production efficiency and operational flexibility. RS-232C serial data, encoder output, and raw encoder output are easily accesssed. An added benefit is through the use of the WL-325A, the 3D lenses can be controlled wirelessly from a distance of up to 300 ft. |
