About Sigma

Sigma is a Japanese manufacturer of photographic lenses and cameras. Our production is based entirely in Japan, with our headquarters in Kanagawa and our factory in Aizu, Fukushima.

We have been a family-owned company since our founding by Michihiro Yamaki in 1961. Today, Sigma is managed by his son, Kazuto Yamaki. It is this independence that allows us to explore different approaches and pursue our ideal of craftsmanship.

Our Aizu factory was established in 1973. To this day, it remains Sigma's sole manufacturing base, with every step of production - from initial concept to optical engineering, product assembly, quality control and even parts sourcing - taking place in Japan. Although not without its challenges, this conscious decision ensures seamless collaboration across departments and partner companies, quick response times and rigorous quality control at every stage of production. Our deep ties to the Tohoku region, particularly Aizu, have allowed us to become part of the local community, to support its culture, to advance local technology, and to nurture the expertise of our employees.

We believe in quality and innovation without compromise. Every single lens, camera and accessory is manufactured to meet our high expectations. For more than sixty years, we have continued to set new standards in photographic equipment, and provide photographers and filmmakers with powerful and long-lasting tools to realize their creative visions.
