“… it means if you’re shooting at 40 feet distance the 70-200 VR II and 2x teleconverter will get you a nice usable image, but not as good as you would get with the 80-400 VR II. The old 80-400 AF lens is better in the center than the 70-200 VR II combination, although that’s just right at the center. Less than 1/3 of the distance away from the center, the two are even.”
