A couple of months ago I did a quick, hand-held, completely non-scientific comparison between the 20MP CMOS in the K-S1 and the 10MP CCD in the Samsung GX-10 version of the K10D. Both shots are with the Super Takumar 20mm/4.5 at f/8 at 1/250 and ISO100. Straight raw to jpeg conversions with no post-processing trickery.
K-S1
GX-10 (identical to K10D)
A few caveats:
The K10D sensor in the GX-10 is particularly well suited to shooting with my beloved Takumars, while the K-S1 sensor seems extremely badly suited to them. The K-S1 gives much more vibrant results with modern lenses, and I never use it with my Takumars anymore.
The K-S1 sensor is not exactly at the bleeding edge of CMOS design. I'd love to see how the K-1's rendering compares with the K10D, but it's out of my price range.
The CMOS shot could be made to match the CCD shot with some work on vibrance and saturation in post-processing, while CCD shots tend to look much better straight out of the camera. My personal impression is that CMOS shots in general need more processing.
So please don't take this as in any way conclusive as a comparison between CMOS and CCD. It's simply my own personal test with the equipment I happened to have to hand
