Lenses of any type are often very complex pieces of equipment. Telephoto lenses often require multiple lens segments all of which are ground to precision tolerances, with only a few microns allowance on the overall dimensions. These then have to be sited inside precision ground bodies full of electonics and ultrasonic motors to move the elements, focus the lens and provide anti-vibration protection.

Have you ever looked at the lens in your hand and wondered ‘Just how is it made?’ Well we thought, as ClickASnap is free photo hosting site with lots of photographers, that you may be interested in seeing just how these lenses are made.

So sit back and enjoy the movie
