I completely disagree with above statement. I wish Pentax did so, but they
didn't.
I'm convinced that Pentax put a heavy anti-alias filter in front of the CCD,
and that's the main reason of all resolution problems (as well as an
excellent cure of the moir� effect, BTW). This is well visible here:

Nothing to do with USM here, just plain MTF capabilities. With the *ist D,
B&W lines merge into gray before other cameras.
IMO, The D1x and the 10D are the winners, while the D70 has the opposite
flaw: too little anti-alias.
