Sigma is a Japanese optical company founded in 1961 that specialises in the manufacture of cameras, lenses, flashes, and other accessories for photography. The family-owned business grew to become one of the largest independent lens manufacturers in the world. Though the company produces many of its own camera models, its most popular products are those that are compatible with other photographic equipment.


Sigma lenses and accessories are compatible with Canon, Nikon, Kodak, Pentax, and other well-known camera companies. In addition to standard lenses, the company offers a number of wide-angle, telephoto, and macro lenses. Their products are available for many types of cameras, including vintage SLRs as well as digital SLRs. Sigma's compact digital cameras are easy to use for photographers on all levels.

About Sigma

Sigma was founded in 1961 and has established a reputation for high quality camera lenses, flashes and other accessories that cost much less than those of Canon and Nikon. It manufactures lenses for the major brands of SLR cameras, as well as making its own, and focuses on semi-professional and professional users that want the best performance at a reasonable price point. The company now produces lenses for Canon, Nikon, Sony, Olympus, Panasonic, Pentax and more, as well as producing lower priced lenses under the Quantaray brand. The mount on its own cameras is physically similar to the Pentax system, but its lenses are designed to fit specifically to other brands. There is a huge range, too, from wide-angle prime lenses through to Superzooms that are aimed at the consumer, rather than the professional, and can technically render a bag full of lenses obsolete. Michihiro Yamahaki founded the company with the goal to create the perfect image and the company is still family-run. It has gone on to become the world's largest independent lens manufacturer and is often considered the only real alternative to Canon and Nikon, despite a number of other independent manufacturers springing up in recent times. There have been occasional problems with quality control, but photography enthusiasts generally agree that if you have a sharp Sigma then it will produce images every bit as sharp and vivid as the much more expensive alternatives.
