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.
