The 60D is much the same. smaller sensors have made great strides, and may look 
noise free at base ISO, but it ain't 
true in the shadows as yet.

Now that would be wrong, as would other lens corrections, in a Raw file. 
Distortion correction is great for many uses, 
but it tends to blur detail in the moved areas. At least that's what I found 
when I tested. It also makes logical sense.

Yes, it would be, is, if it's happening. Pixels shouldn't be moved around, 
stretched and compressed laterally in a Raw 
file. They start doing that, and I'll join AG's camp.
