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.
