Digital BW, The Print

This lens does offer very good performance though--and its been a favorite of Canon photographers over the Canon 20.   Just depends upon whether you want a zoom or not.  Not having tried the 10-22 I'm not sure, but I prefer a faster lens for some purposes so will certainly not drop this lens.

  After 24 mm the full frame wide angle lenses seem to get very large, heavy,
  and expensive, with usually less than great performance.  Retro-focus lenses
  have never been a favorite of mine, and the wider they get, the poorer their
  performance seems to get, all else being equal.  So, I think using a
  full-frame, radical retro-focus design on a 1.6x sensor is a temporary patch
  that doesn't make long term sense unless one just happens to have one lying
  around.

  Yes, this is the way to go for this camera if I want to go wider.  I've seen
  some comparison shots with this lens and the third-party versions, and the
  Canon looks way better.
