How camera lenses are made

John Watson // January 25th, 2008

From the markings on the barrels, these appear to be lenses made by JML Optical. It shows how painstaking it is to make high quality lenses. I thought it was interesting to see the strange mix of high-tech (vacuum chambers and electron beams) and low-tech (wooden sticks and plastic cups) manufacturing methods used in the production of one lens.

   Thank you for sharing, John. I have a background in manufacturing engineering, so this stuff always interests me. For the operation they had, the thing that really seemed inefficient was the markings on the barrel. What a slow process.

   It makes you appreciate the cost of Nikon and Canon’s nifty fifty.
