If you’ve had the chance to work with a 3D Camera rig then you probably take the lens for granted, not realizing the huge amounts of effort and skill that go into creating it. In a new article on Broadcast Engineering world they go in-depth into the creation of stereo 3D lenses, and the article will give you a newfound respect for the engineers that create them.
It takes many man-hours to handcraft a single stereo 3-D telephoto lens, with technicians who are experts in optics handcrafting them. Most of the time is devoted to repeated analysis and testing of the lenses, and then putting them back on the workbench for further refinement until tight tolerances have been met.
