The new flagship Sigma SD1 DSLR is at the heart of the extensive system of precision optics and advanced accessories. Built around the latest Foveon image sensor, the SD1 is designed for professional use. Among the camera’s features are 46-megapixel resolution, Sigma True II image processing engine and solid magnesium construction that’s also dust- and splash-proof.

The Foveon sensor in the Sigma SD1 is unique among DSLRs. Other manufacturers use monochrome CCD or CMOS chips that require color interpolation to build a final image. The SD1’s full-color 46-megapixel Foveon sensor captures all colors on every photosite. Red, green and blue color information is captured on each of the 15,000,000 pixel locations, which allows each pixel to provide both full luminance and chrominance information. This creates a more realistic and natural-looking image. The Foveon sensor is the only one made that can capture both luminance and chrominance information in this way. Other sensors have to reconstruct luminance information that’s lost due to their bayer-pattern arrays. Sigma technology preserves color and contrast relationships in every image.

To create a fine image, all of your gear needs to work together. The lens, DSLR and accessories fuse together into a system that performs in concert to generate the photograph. No matter how good an image sensor is, if the lens mounted to the camera isn’t at the same level, you won’t get your best images. Advanced optics like the 24-70mm ƒ/2.8 EX DG HSM zoom and the 30mm ƒ/1.4 EX DC HSM prime lens perfectly match the SD1 and its game-changing technology. The photos are stunning. The Sigma System delivers with rich, vibrant, luminous colors and the highest image quality possible.
