lensmaking

On January 28, Nikon announced the 80th anniversary of the launch of the Nikkor lens brand, and that the total number of lenses manufactured since the beginning has exceeded 75 million units. The lineup now includes more than 80 types of lenses.

To celebrate the occasion, Nikon released the above video, which offers a behind-the-scenes look into how its widely used lenses are made. The video starts from the production of the glass from sand and goes through final assembly, all in three-and-a-half minutes.

We showed you Nikon's video earlier today, now it's Sigma's turn to show what goes into making quality lenses at the company's factory in Aizu, Japan.

Filmed from the same artistic bent as the Nikon piece, this video show the meticulous process that goes into making quality Sigma glass. Unlike Nikon's version, this one doesn't stop until the lens is fully assembled and ready to latch on to the nearest camera.
