They can update some but not all of their lenses.  I called Sigma.  The 24
mm f2.8 I have is too old.

I'm OK with the 18 - 55 that came with the camera at this point.  The 24 mm
was not really as wide as I like anyway.  While the auto depth of field
feature on the Rebel XT appears to be close to random and useless, I've got
the DOF down now.  Some charts and tests allowed my to slap some scales on
the lens, making it quite feasible for the zone focusing I like.  And this
little puppy really has some DOF.
