Suitable isn't the same thing as "optimal". Remember, Canon is in the
business of selling people things, They sell you a 17-40, then 4 years
later they come out with a "digitally optimized" version and get to sell
another batch of the same focal length lenses. Watch and see if this
doesn't happen.

Here's what the Canon Camera Museum blurb has to say about the 17-40 L we've
been talking about...
"Featuring a new optical system design, the new lens delivers an expanded
zoom range of 17-40mm, with the wide-angle-end 17mm focal length making it
ideally suited to digital photography." I wonder what their idea of "works
ok, but not great" is...
I know they're talking about focal length, but still...
