How Canon Manufactures Their Camera Lenses

Virtual Lens Plant

Canon has a Virtual Lens Plant on their website that includes some great videos showing the manufacturing process behind creating their camera lenses. The example lens they use is the EF 500mm F4L IS USM. I own several lenses for my Canon 5D and it’s great to see the step-by-step process that goes into making each lens.
