Sigma SD9 3.54MP Digital SLR Camera description
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.

The sharpest images you can produce

I'm a bit late in writing this review since I've had my SD9 for one year.

The image quality of photos using the SD9 can be quite stunning. The level of sharpness achieved by the Foveon sensor is amazing - it can resolve detail that Bayer sensor cameras (all other digital cameras fall into this group) simply cannot. Couple this camera with one of Sigma's "EX" lenses, particularly the super-sharp 50mm EX macro lens, and you'll love the results. I enjoy macro photography and this camera is excellent at macro photography.

I'm certainly not in the league of a real photographer as I'm just a casual type who enjoys taking pictures. As they say, the proof is in the picture and I've seen the proof! Forget about the megapixel rating and the fact that the Sigma is "only" 3.4 MP. The Foveon sensor has 3.4 million photosensors for each primary color - that's 10.2 total MP - while a 6 MP Bayer sensor has 6 MP for all three primary colors.

Why a four star rating rather than five? This camera is not without it's issues, like all cameras. The SD9 is not a very good low-light performer. If you need ISO speeds faster than 100 then the SD9 may not be for you. High ISO shots are noisy although you can get very usable high ISO photos if the conditions are ideal. The SD10 addressed this issue. The SD9 does not have a built-in flash but those units are not suitable for serious flash work anyway. This camera can only use Sigma SA mount lense so the choice in lenses is not as wide as for a Canon, Nikon, or Minolta user but Sigma makes some very, very good lenses and they certainly offer more choices than I can avail myself of. If you want in-camera jpg files, look elsehwere. The SD9 shoots only in RAW format and you have to process the photos. This is actually the best way to shoot, there is so much that can be done with a RAW file that one cannot do with a TIFF or jpg. The Sigma Photo Pro software is a gem of an application that is extremely powerful and easy to use.

Again, look at the results and you'll see that this camera is an extremely capable performer.
