It's finally here... Nikon's AF-S 70-200mm f/4G ED VR !!!

At 200mm it's better than the 2.8 at the edges but is similar in the central zone.  This is comparing images at f/2.8 with f/4 so the new lens doesn't really win here.

At 70mm the 2.8 looks better at 2.8 than the 4.0 at 4.0 so by MTF the new lens isn't even close.

I'm hoping that it's optically better when tested in the real world than the MTF seems to indicate.
