Here's a calming video showing how Sigma makes a 70-200 lens
In the age of highly produced and dramatic videos, sometimes it's nice to have something simple. This video of the Sigma lens manufacturing process is just that. Coming from the YouTube channel ProcessX, the video shows the Sigma 70-200mm F2.8 DG DN OS being made in the Sigma Aizu factory in Bandai Town, Japan. It walks through the entire process, including the coatings that go on the glass, lens bonding, quality control and more. The captions provide some context, but there's no voiceover. It's just a soothing, ASMR-style video that shows the incredibly complex process of putting together a lens. Zoom lenses offer their own build challenges, of course, so it is always impressive to watch how so many components fit together to create a quality optic. You can check out our sample gallery of the Sigma 70-200m F2.8 DG DN OS to see the results of the production process. DPReview also had a chance to tour the Sigma Aizu factory back in 2019, though with a focus on the Sigma fp assembly process.
