SIGMA SD15 Lens System

High-performance Sigma lenses

Founded in 1961 as a lens manufacturer, Sigma has leveraged its original technologies to create unique products and assume its position as a leading photographic equipment provider, despite a relatively late start in the marketplace. Today, Sigma continues to be a leader in the highly competitive interchangeable lens market, thanks to its dedication to ongoing development of innovative products and an unstinting approach to quality control.

Today the standard for SLR cameras, the rear converter was originally a Sigma invention. A front conversion lens had to be designed specifically for a single master lens and tended to make the camera front-heavy. The rear conversion lens, inserted between the lens and the body solved both problems. Sigma’s innovation led to the user-friendly lens system with which photographers are familiar today.
