The excellent William L Castleman didn't specifically test for light fall-off.
You need specialist equipment to measure it.
As you know Canon use the market to beta test their products. Only after the
24-70 hit the market did it receive the baptism of fire. Also the higher res
the camera so defects become more obvious as shown with the D1s2.
Canon are now well aware of the digital full frame requirements and will
design
for it.
I expect the new 24-105 f/4 L IS to make a super kit lens with the 5D. Will
make a killer combination for wedding large group shots and landscape
photography.
Would be the equal picture quality wise to the D2X with 17-55 f2.8, but much
better in low light.
