Sigma founder and CEO Michihiro Yamaki died of liver cancer in Tokyo, Japan, on Jan. 18 at the age of 78.
“Mr. Yamaki was an industry visionary, and his leadership and enthusiasm has been the driving force behind our company’s innovation for more than 50 years,” the company says.
Yamaki founded Sigma Corp. Sept. 9, 1961. with the development of the first-ever rear attached lens converter, the company adds. “At that time, most photo enthusiasts believed a lens converter could only be attached to the front of a camera lens. The 27-year-old optical engineer turned conventional optical theory on its head.”
