CA correction also has the added effect of increasing sharpness throughout
the image, despite the fact you don't see the fringes, which can be a good
thing for wide angles.
It wasn't asked, but for the canon side the 10-22 is awesome. I've asked
around if the full frame version.. I think it's the (16 or 15)-35 2.8 is as
good, and I can't seem to find anyone with a good answer except for it's L
and 2.8 so buy it. They would have the same FOV. I've heard it that the
10-22 uses the same glass composition as an L lens. I think my primary
argument would be that on a crop camera the center optics are used more than
the outside optics like a full frame ccd would show.. So it could be a toss
up for quality, or not. I'd really like to know.

I don't find post processing at all "interesting" and it might give
you an idea of the extent of the CA problem with this lens if I tell
you that I never bother to remove it. I did, once or twice, to see
if there was any significant difference. The answer is "no."
As I said above, you can FIND it, but you have to LOOK for it.
