When it comes to high-quality photography, cameras, lenses and flashes, SIGMA is a must. The name Sigma stands for the result of high technology, know-how and experience. The company chose its name for a reason. Sigma is based on the Greek letter S, which in mathematics stands for total sum. The corporate philosophy expressed by this name has been consistently applied in the development and production of all SIGMA products since the company was founded about 50 years ago. Not least for this reason SIGMA is today one of the leading manufacturers of lenses, cameras and flash units. SIGMA (Deutschland) GmbH was founded in 1979. Based in Rödermark near Frankfurt, it serves the company's leading market in Europe and the third most important market in the world.
