The first 2 questions in this thread have been asked so many times in so many places that I believe they demonstrate a sufficient level of interest so as to be considered "of general interest", ...not "pixel peeping"(heaven forbid).
I hope they may be addressed.
It seems that the CCD vs CMOS question bears on this question in many readers' minds.(i.e. the new 1D is DIFFERENT in that respect, ...so what is the practical effect, if any, on out-of-camera sharpness, ...and to what degree is this under user control?)
Sorry, but I really object to "politically-correct"/or-not handy-but-not-dandy classification of areas-of-interest.
("Gee, is this a PP question, ...or not?"" Is it OK if I ask it?")
