this one has a different sensor on it. Is there any benefit in having all 3 colours on one pixel?
FOVEON X3(R) Direct Image Sensor
Foveon X3(R) direct image sensor in the Sigma SD10 digital SLR can capture all RGB colors at each and every pixel. The revolutionary design of Foveon X3® direct image sensor features three layers of pixel sensors
Using three silicon-embedded layers of pixel sensors, stacked to take advantage of silicon's ability to absorb red, green, and blue light at different respective depths, the Foveon X3® direct image sensor can thereby directly capture full color and detail at each and every pixel location, without interpolation.
Other conventional image sensors feature just single layer of pixel sensors in a tiled mosaic pattern. Each pixel detects only one color of light, which has been filtered through a single red or green or blue color filter. As a result, two thirds of the color information at each pixel is blocked out. To compensate, the missing color is estimated through a complicated process of color interpolation, leading to color errors, color artifacts and loss of image detail.
Sigma SD10, powered by Foveon X3® direct image sensor, however, captures all three colors at every pixel location, ensuring the capture of full, complete color. It efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor.
