Any theoretical conclusions can be drawn from these charts?
Wide open (f4), the 24-70/4L has a comparable performance to the 24-70/2.8L II wide open (f2.8).
This is more of a testament of how good the 24-70/2.8L II is.
Still, the MTFs indicate that the 24-70/4L will be very sharp wide open - all the way to the corners.
Stopped down (f8), the 24-70/4L is actually sharper than the 24-70/2.8L II at 70mm.
Both are the same at 24mm.
Note, though, that the MTFs say nothing about distortion.
EDIT: fixing my previous post, as I was looking at the wrong charts.
