Perfect images are generated by the Foveon X3 direct image sensor and a complete lens system. Sigma's technology advances, but its photographic philosophy remains the same.

Sigma's SD15 SLR camera is the latest model in Sigma’s SD series. Powered by the 14 megapixel Foveon X3 direct image sensor it can capture all primary RGB colors at each and every pixel location arranged in three layers. The new SD15 incorporates the "TRUE II" image processing engine which processes the large amount of data from the 14 megapixel direct image sensor. It also provides high resolution power and reproduces high definition images with impressive three-dimensional detail, rich in gradation. The camera adopts the SD card and incorporates a highly visible 3.0 inch LCD monitor, 77-segment AE sensor and AFE (Analog Front End). It provides high image quality and user friendly design. In addition, the durable shutter mechanism, which has a life of over 100,000 actuations, is ideal for the demand of digital photography.

Since October 2002, Sigma has introduced three digital SLR cameras, the SD9, SD10 and SD14. The SD series has established a strong following from a wide range of photographers, both amateur and professional. This new SD15 has been developed with the principle of producing superior image quality from the direct image sensor, as well as improved processing speed, operation and performance.
