Early Adopters Pick: December 2002. Powered by Foveon X3 image sensors, the world’s only technology that captures red, green, and blue light at each and every pixel in three distinct layers.
The breakthrough Sigma SD9 high-definition, digital single-lens reflex (SLR) camera contains the world's first image sensor to feature three layers of photo-detectors. The camera’s SLR system can take advantage of over 30 different lenses, from 8mm circular fisheye to 800mm ultra-telephoto, plus two digital flashguns, power pack, and accessories.
Optics and Resolution
The Sigma SD9, powered by the Foveon X3 image sensors, captures red, green, and blue light at each and every pixel in three distinct layers. All other image sensors feature just one layer of photo-detectors, with just one photo-detector per pixel.
The SD9's three layers are embedded in silicon to take advantage of the fact that red, green, and blue light penetrate silicon to different depths, allowing full color to be measured at every pixel. This means that for every pixel on a Foveon X3 image sensor, there's actually a stack of three photo-detectors, forming the first and only full-color capture system.
Storage and Transfer
The SD9 uses CompactFlash memory cards and is compatible with CompactFlash Type I/II cards, which enables you to use IBM Microdrives as well. You can transfer the images from camera to computer with high-speed IEEE 1394 (also known as FireWire) and widely available USB (1.1) interfaces. The camera's video-output system can be switched between the PAL system (used in Europe) and the NTSC system (used in Japan and the U.S.).
Image Format
With the RAW data recording system of the SD9, it is possible to obtain high-picture definition and compact file size. The lossless compression system of RAW data eliminates image deterioration, and provides superior pictures, without sacrificing original image quality.
More Features
The SD9 is equipped with a large 1.8-inch, 130,000-dot low-temperature polysilicon TFT-LCD monitor with a white LED on the back panel, which displays images, menus, and histograms.
The SD9 is equipped with a "sport finder," so you can easily follow the situation outside the picture area. The area that is out of the image sensor’s coverage range is marked by transparent light gray, to distinguish it from the active picture-taking area.
Dust and dirt entering through the lens mount of a digital camera can create serious defects in image quality. In order to prevent dust entering and adhering to the image sensor, the body mount of SIGMA SD9 is equipped with an integral dust protector.
Power, Size, and Contents
The SD9 comes equipped with four CR-V3 batteries and an AC adapter; you can also use four optional rechargeable NiMH batteries to power the camera. The SD9 measures 5.9 by 4.7 by 3.1 inches and weighs 28.3 ounces. Other standard accessories are a hand strap, CD-ROM with imaging software, USB cradle and cable, AC adapter for cradle, remote controller with LCD, and stereo headphone.
Product Description:
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. Using FOVEON X3 technology 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.
