Sigma SD1

In a revolution, you need to have radical technology on your side. Photographers Of The World, Unite!



The world of professional photography is being turned on its ear. A new generation of professionals is taking the reins and driving the revolution. The Sigma System is available to completely change the game. Nothing matters more than image quality, and the new SD1 was created to give you rich, vibrant, luminous colors and the highest image quality possible.

The Sigma System

Sigma's line of professionally oriented products is extensive. From the flagship SD1 DSLR to the fast prime and constant-aperture zoom lenses, Sigma makes a complete system designed from the ground up for professional photography. For example, the SD1's revolutionary sensor technology matches up perfectly with the 24-70mm F2.8 EX DG HSM and 70-200mm F2.8 EX DG OS HSM zooms and the 30mm F1.4 EX DC HSM and 85mm F1.4 EX DG HSM prime lenses. These lenses synergize with the Sigma SD1 to produce images with the finest sharpness, contrast and detail you can get, period. The sensor on any digital camera can only perform as well as the lens that's in front of it. The Sigma System doesn't compromise on image quality because you can't afford to either.
Color Is Paramount
The Sigma SD1 delivers uncompromising color fidelity no matter what you're shooting. Using three silicon-embedded layers of photodetectors stacked vertically to take advantage of silicon's ability to absorb red, green and blue light at different respective depths, the Foveon sensor efficiently reproduces color more accurately than any conventional sensor.

The new Sigma SD1 was conceived to give professional image makers the richest colors and highest overall image quality. From its one-of-a-kind Foveon sensor to its Sigma SA-mount, the camera proves that history isn't made by playing it safe. The SD1 dares to chart a path away from the camera technology mainstream. Instead of the usual CCD or CMOS monochrome sensor with color filters, Sigma took its own path. The radical Foveon sensor in the SD1 records all color information at each pixel instead of the usual Bayer-pattern color filter array and sharpness-killing interpolation.
46-Megapixel Resolution For Massive Prints
That's not the only revolutionary aspect to the SD1's newly designed sensor. The radically new DSLR has a high-resolution, low-noise, 46-megapixel, APS-C direct image sensor (4,800 x 3,200 x 3). The SD1 creates RAW images of about 48 MB, which open up to nearly 100 MB 16-bit TIFF files. This means an incredible ability to make high-quality enlargements comparable to much larger, more expensive image sensors. The SD1 has the ability to create RAW files, simultaneous recording of RAW + JPEG, and variable-size RAW files when very large files aren't required.

Ultimate Detail
Conventional digital SLR cameras using CCD or CMOS sensors with Bayer color filters are susceptible to annoying moiré patterns when photographing subjects with fine detail, so they incorporate a special low-pass filter to minimize moiré effect. But this filter simply blurs detail and reduces sharpness. Since the unique Foveon sensor doesn't use these filters, subjects can be recorded with much finer detail, which results in an image with realism and depth.
