Officially launched in February, 1984. To cope with many demanding action activities in particular in the context of sports and wildlife photography, this lens has a single ring for responsive focusing/zooming control which provides extra handling speed and time for picture framing and composition. This remarkable Nikkor zoom lens incorporates some of the original Nikon optical innovations such as Extra-low Dispersion (ED) glass and that superlative coating which keeps ghosting and flare at bay. The use of FOUR ED glass elements in the optical design delivers crystal-clear images even when use at near maximum apertures and ensures minimized chromatic aberration while at the same time, delivering high edge-to-edge resolution throughout the focal length range . Nikon’s lens coating process also improves the picture contrast and colour rendition over the entire 200-400mm zooming range. For increased convenience and flexibility, an L-shaped rotatable tripod collar with three screw-in tripod sockets helps achieve optimum balance for motor-driven photography and enables the photographer to switch quickly from horizontal to vertical format shooting.
