Digital photos have never looked quite as good as those taken on film. Until now.

 

Only the SIGMA SD9 digital single-lens reflex camera makes this major breakthrough.

D i g i t a l

Using FOVEON® X3technology with over 10.2 million pixel sensors for more accurate, efficient color

reproduction, and sharper resolution, pixel for pixel, than any conventional CCD or CMOS image sensor provides.

 

So you can capture more of your vision in a truer light.

 

Go ahead. Get more creative. The SIGMA SD9 puts the advantage of

 

higher technology right in your hands.

FOVEON® X3image sensor brings new vision to

digital imaging.

The FOVEON® X3image sensor is the heart of the first

and only full-color capture system for digital cameras. The X3. image sensor uses three silicon-embedded layers of

pixel sensors, stacked to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths. A FOVEON® X3image sensor can thereby capture full color and detail at each and every pixel location.

The results are a revelation : better color detail, fewer color artifacts and three times the image sharpness, compared to that delivered by more conventional image sensors.

true full - color capture system

Unlike the SIGMA SD9, other digital cameras’ image quality is inherently compromised. Conventional image sensors use

a single layer of pixel sensors which are organized in a three-color checkerboard mosaic. Each pixel location has one pixel sensor and captures just one color component — red or green or blue. Regardless of pixel count, mosaic-based image sensors capture only one-third of the information that FOVEON® X3full - color image sensors capture per pixel location, and rely on complicated time and energy- consuming processing to interpolate the two - thirds of all the information they miss at each pixel. This leads to color artifacts, loss of image detail, and other disadvantages.
