Press release:
Kawasaki, Japan, November 11th, 2008 - Sigma Corporation (Location: Kawasaki, Japan) has acquired 100% of the stock of the company that developed the original three-layer image sensor, Foveon Inc. Foveon will continue its sensor development operations in San Jose, CA, USA.
Foveon made history when it developed and patented the world’s first three-layer image capture technology, placing a stack of RGB pixels in each pixel location. As a result, Foveon sensors detect all three primary colors in every pixel location, producing images that are sharper and have significantly reduced image artifacts compared to competing image sensor technologies.

Sony A900 Review by DPReview:
In conclusion this is, more than anything else at this end of the market, a true photographer’s camera, with at least one totally unique feature (the Super SteadyShot stabilization) and one that offers the best viewfinder and highest nominal resolution (and the lowest ‘cost per megapixel, incidentally) in its class. It’s capable of stunning results at up to ISO 400 (and is fine at ISO 800-1600 as long as you’re not printing posters), and it is incredibly fast and responsive in use. If Sony had managed to keep the price nearer to the $2000 mark (even if this meant fewer megapixels) I think it would be flying off the shelves. As it stands it will, I fear, struggle to make a serious impression on anyone other than the Sony/Minolta faithful. One thing is clear, however: anyone who thinks a consumer electronics giant can’t make a heavyweight photographic tool is seriously misguided.
