CANON　LENS　MAKER　2

The best commercial lenses are made in the states, why else would Sony and Mitsubishi be our biggest clients ?

Hi batiendo, At 1:26 into the video, they are shown optically testing the lenses. They are testing their quality using a Zygo interferometer, made in the USA. The best lenses are made by the people doing the best job, wherever they work.

NOT REALLY, NOT IT ISNT. All commercial grade lenses are developed in the states. Our biggest client is actually Sony of japan.

Polishing on concavity pads, alignment with a microscope and cutting down with a die. In Chicago, our alignment microscope is built into our lathe. Our electrolysis-vacuum stove also carries more lenses.
