Digital BW, The Print

Austin, 

The D30 and D60 use a CMOS chip and not a CCD.

  Of course.  Line art images are extremely sharp too, but they have no detail
  or tonality ;-)  To me, sharpness isn't an indication of "good" or
  "quality".  If there were tones in the original image that aren't duplicated
  in the recorded image, information has been lost...though the image may be
  very sharp.

  What size prints?  For a 4x6, no doubt, and for even some 8x10, but for a 13
  x 19, well, been there, done that...have some on my photo board.  Not even
  close.

  It depends on what you mean by "great".  It WILL be sharp, but it WILL not
  contain the same detail as a print made from film.  It physically can not,
  and really doesn't.  I've been doing this (digital imaging) for a long time,
  and I have a number of digital cameras.  I know the results.  The D-30 isn't
  magic.

  Same here.

  If you believe it works for you, that's good!  I am not saying it doesn't
  work for you, as only YOU know that.  But, I'm saying your conclusions as to
  "quality" aren't the same as mine.

  Me too ;-)

  Well I CAN see the loss in "quality", as well as many other people can.  If
  sharpness is your primary indication of "quality", then you're going to have
  a different conclusion than someone who has some other property as their
  primary indication of quality.  "rezzing up" an image does NOT provide
  detail that simply is not there in the first place in the recorded image.

  Bingo!  And that's what matters to you.

  There's actually something "funny" about that.  Sharp lenses mean nothing on
  this camera.  The issue is there is a "low pass" filter (some call it
  "anti-aliasing" filter) between the lense and the CCD.  Why this is
  important to understand is this filter actually "dumbs down" the lense so
  the MTF of the lense matches the CCD pitch.  The sharpness of the lense, on
  that camera, really doesn't matter...you'd probably get equally as good a
  result with a Sigma or Tamaron etc. lense, than a high end piece of glass,
  as far as "sharpness" goes that is.

  Actually, that's is not true, as I stated above.  Most of the web sites that
  talk about this stuff acknowledge this readily.  Even DPReview says that the
  D-60 is probably the first digital camera (as far as the 35mm-esque
  varieties) that the lense might actually matter ;-)
