The breakthrough Sigma SD9 camera features the FOVEON® X3TM image sensor which is the world's first image-sensor that features three layers of photo detectors. The 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. The layers are positioned to take advantage of the fact that silicon absorbs different colors of light at different depths, so one layer records red, another layer records green and the other layer records blue, This means that for every pixel on a FOVEON® X3TM image sensor, there's actually a stack of three photo detectors, forming the first and only full-color capture system.

Pros: Very Sharp images. Excellent for capturing solid objects. Foveon Chip
Cons: Not recommended for portraits. Only saves to raw format. Yellow cast on images.
The sigma camera has the distinction of being the only
digital camera that is currently using the Foveon X3 Pro 10M chip. The technology delivers sharper
images than most digital cameras. Moreover you can make prints as large as a1 from the sd9 files. Although you can take sharp handheld shoots with this camera, the handling of this camera is not very user friendly when compared to cameras like the Nikon D100 and the Canon 10D. This is important cause you want to hold the camera as still as possible when shooting so you can get sharp images.
The Sigma's SD9 gives all your portraits a yellow cast.
It also does a poor job of capturing denim.
plus it's noisy at iso above 100. Sigma is the only company that make lenses for this camera so your options are limited.
