Can anyone explain what special magic Canon is doing with the new 5Ds and 5DsR as far as color is concerned? And what the differences between the two cameras are? I am a little confused about the way it handles color. I saw the video with the engineer explaining it, but it's still a little cloudy to me.
Thanks.
Thanks.

It seems that the 5Ds and 5DsR have stronger color filter arrays for more accurate color rendition, like the 10D and Digital Rebel had before the newer emphasis on quality in low light.
The language being used about the low pass optical filter leads me to believe that the 5DsR possesses digital post processing in camera that deconvolutes the effects of the low pass filter. So this camera has some of the post processing power that Canon put into its DPP post processor.
It is only possible to partially undo the effects of the low pass filter with digital post processing because only amplitude information is available then, while the optical low pass filter uses phase information as well to do its job. And I would hope that color moire is still suppressed.

The stronger the Bayer filtration and CFA, the poorer the noise and DR is. No free lunch

In short, trading off high iso performance for high color depth at low iso levels. Colors will be more rich and "pop" compared to, say, a regular FF body. But you pay for that with noise above base iso.
The R variant delivers slightly greater resolution, although I would argue that only very specific needs calls for such a body. No AA filter is always nice, but the difference only really shows up when you're printing.

Thanks for the information guys. Makes a lot of sense to me now.

A minor correction... the reduced analog signal levels and increased puity of RGB color filtration affects all ISO settings. As the signal to noise ratio decreases (due to decreased exposure) the degredation of shadow region IQ may be more apparent when ISO is used to brighten the image after the shutter closes.
