Anyone thought of this in relation to the Canon 5d mark 2

No one (apart from Canon) has seen what the corner shading will be like with the 5d Mark2. Will better lenses be needed?

The camera supposedly has built-in auto-correction for vignetting (corner shading). I think that this actually means we can actually use lesser quality lenses.

What does lesser quality lens have to do with that. Wide ap lens usually suffer from light fall off in the corners and this helps correct the exposure in the corners..This really has nothing to do with lesser quality lens

A feature called periperal illumination correction which, I believe, first appeared in the 50D can be used to correct for the corner shading you are referring to. This feature uses a database of Canon lens optical characteristics to compensate for the light falloffs in th corners. Because the lens information is provided by Canon, I'm thinking this feature won't work with 3rd party lenses.

I may be incorrect, so, feel free to educate me. I was under the impression that the higher the quality of the lens, the less light falloff it would have, as a general rule. Logically, it seems that lower quality lenses would most likely suffer from more light falloff at the corners.
