Canon Lens Plant Tour

I don't know as much about it, but optics are also an area I find very interesting. I took Engineering Physics in college and have since forgotten much of it, but I have a great appreciation for the engineering that goes into anything dealing with light and also sound. While looking for lens information I found someone who stated that he "believes Canon is the only camera company that manufactures all their own lens elements from raw materials (at their Utsunomiya plant). Leica makes lenses too, but they also OEM out some of their lenses entirely."

This Canon plant tour shows all of the steps to create a camera lens from start to finish, and the featured product the EF 500mm F4L IS USM is a gigantic lens at 19.7 inches in length! Also be sure to check out the Lens Gallery at the bottom which has more information about lens materials and physics.

You seem to know a bit about lensmanufacturing. Do you have any hints on where I can find a manufacturer of OEM snap-on fisheye lenses for my brand?

If you do, please contact me at jakob.nordstrom at gmail
