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.
