Why? Because the green and red sensors are deep within the chip rather than on the surface. If you want to really see color fringing out on the edge of a digital photo, using a wide angle lens, just use a Foveon chip. I have a friend that works at Foveon and have seen the results first hand. Or you can go buy a Sigma/Foveon and see for yourself. http://www.foveon.com/X3_tech.html The only answer to the wide angle lens - sensor acceptance angle problem is to design digital specific lenses which have a collimator lens at the rear to re-angle the light rays straight down onto the sensor. One lens manufacturer is already doing this.
