Σ SIGMA is the Greek letter equivalent to the English letter "S." In mathematics, it's a sign used to show the total sum. For photographers everywhere, Sigma is the total sum of the research, development, manufacturing and service of the world's leading line of lenses and cameras.
After more than 50 years of pioneering new and better ways to capture and portray the ordinary — and extraordinary — Sigma is still creating new avenues of expression with innovative designs and enhancements in zoom and non-zoom lenses, and digital cameras.
Products you and millions of photographers worldwide turn to when quality, reliability and professional results count most. Every Sigma product is 100% made in Japan, and products purchased in Australia come with an official two year warranty.
