Thanks for sharing your test results. Yesterday, I was very happy with my decision to be an early adopter of the 24-70/2.8L II. Today, I'm still very happy with that decision.
The new 24-70/4L IS shows excellent distortion performance, and it has usefully better resolution than the venerable 24-105/4L IS at common focal lengths. In fact, it has the best distortion and next-best resolution (to the 24-70 II) in all test conditions.
I'll be keeping my 24-105L for walkabouts, because of its extra reach, and decent resolution, but if I didn't already have the '105L, and I wanted a high quality, light weight, normal zoom, I'd seriously consider the 24-70/4L IS.
It would be very interesting to compare effective reduction in resolution involved with distortion correction in PP for the 24-70/2.8L II and 24-70/4L IS, given the 24-70/2.8L II higher resolution and the 24-70/4L IS lower distortion. I'm just sayin'...
P.S. Fred, thanks for keeping us up-to-date on this kind of info.
