Nikon today announced a new super telephoto lens for DSLR cameras. The AF-S Nikkor 200-400mm f4G ED VR II is meant for professional photographers who need a very long reach but don't want to compromise on the body or optics. At a constant f4, it has a relatively wide aperture even at the far end of its reach. It comes in a magnesium, weather-sealed frame and as its name implies uses both vibration reduction and extra-low dispersion glass to reduce blur or chromatic effects.
