Last year Sigma released "Sigma Aizu," an unexpectedly captivating video showing how the company manufactures their products. It was not only a rare look into the process, but also done in such way that mirrors Sigma's recent change in their attention to detail and love of the craft. Part 2 was just released, and it matches the artistic integrity of the original.
Our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. To pursue optimal quality, the vast majority of Sigma's manufacturing right down to molds and parts - is carried out under an integrated self-manufacturing production system, within the company.
The overarching theme and message here is that the video is Sigma. Their values, their precision, and their attention to detail. And yes, this video (as well as the original video) was all shot on Sigma glass.
