The Sigma Advantage
Technology and Innovation
Sigma was founded, nearly 50 years ago, on the creative thinking and the pursuit of innovation, design and development of a rear lens converter, which, at the time was thought not possible. That perseverance, commitment to new photographic developments and high standards of quality is what drives Sigma, still, today. The chairman and founder, who remains at Sigma's helm even today, continues to drive Sigma toward designing and discovering new optical technology that meets the needs of today's ever changing photo world and the demands of the photographers themselves.
Sigma Lens Quality
Sigma lenses provide the highest optical quality coupled with the newest technological innovations. Quality is never compromised and always the focus. Every phase of research, design, processing and production is done, on site, in the Sigma Tokyo factories. This allows the highest degree of quality control ensures a high, consistent level of quality as we process all of our own high-performance Special Low Dispersion glass (SLD), metal and resins, surface treatments and other elements.
