Thanks Marty.

The "fine detail" and "color" rendering is what I see
differentiating the CCD's in the M8 and DMR and the Cmos in the 5D.

The way that translates (for me) in actual prints:
the CCD offers (to my eye) a more "traditional" photographic look in  
the print;
the Cmos offers (to my eye) a smoother "digital" (some say plastic)  
look in the print.

Obviously these are subjective calls.
