Really? the RHS is the F4 lens? Were these both shot at F4 or were they both shot wide open(same thing for the F4 lens obviously)? If the former then this is very good for the new lens but I am surprised that the F2.8 is so poor. Is an error of technique possible?
The shots were tripod mounted, and focused via magnified live view. VR was turned off, and the camera was set to mirror lockup. I waited roughly 3 seconds to trigger the shutter after engaging mirror lockup with my MC-30 remote. With all the various setups I've shot, this is the pattern I've seen. The f/4 version tends to be a hair sharper at f/4 than the 2.8 VR. By the time you reach f/8, they are roughly the same. I've done all my testing at 200mm.
