Digital Photography Review has an in-depth look at the 3.43-Sigma SD9, the first digital camera to use Foveon’s X3 imaging technology,which captures red, green, and blue light with every pixel, rather than other sensors in which each pixel can only record a specific color. Apparently X3 lives up to the hype, as Digital Photography review says that the SD9 has “The best resolution per output pixel we’ve ever seen.” This type of technology will probably find its way into most digital cameras eventually.
