Nikon 400mm f/2.8G IF-ED AF-S VR Nikkor

(From Nikon lens literature) Nikon has announced three new AF-S super-telephoto NIKKOR lenses -- the AF-S NIKKOR 400mm f/2.8G ED VR, AF-S NIKKOR 500mm f/4G ED VR, and AF-S NIKKOR 600mm f/4G ED VR -- to further strengthen its super-telephoto lens line-up. With unprecedented image quality, responsiveness and versatility, these new NIKKOR lenses are certain to set a new benchmark for super-telephoto lenses.

The new super-telephoto lenses are equipped with a Vibration Reduction (VR) function. Nikon's VR II system minimizes image blur caused by camera shake, offering a shutter speed up to the equivalent of four stops faster. The newly added Tripod mode reduces vibration that may occur when shooting with a super-telephoto lens when attached to a tripod at shutter release time. Nikon's VR function also gives photographers the option of a natural viewfinder image even during VR operation.

The superior functioning of the newly developed optical system ensures flawless synchronization with Nikon's digital SLRs. The new optical design features three Extra-low Dispersion (ED) glass elements that minimize chromatic aberration while producing consistently high-quality images. The Nano Crystal Coat -- extra-low refractive index coatingc --- virtually eliminates internal lens element reflections across a wide range of wavelengths and is particularly effective in reducing ghosting and flare. A meniscus protective glass element also minimizes the ghosting that occurs when light is reflected from a digital camera image sensor and in turn reflected off an ordinary flat protective glass element.

Nikon's exclusive Silent Wave Motor (SWM) provides fast autofocus with superior accuracy and ultra-quiet operation. All lenses feature nine-blade rounded diaphragms that ensure a more natural look for parts of a scene intended to be out of focus. The minimum focus distances are 2.9 m/9.5 ft, 4.0 m/13.1 ft and 5.0 m/16.4 ft for the AF-S NIKKOR 400mm f/2.8G ED VR, AF-S NIKKOR 500mm f/4G ED VR and AF-S NIKKOR 600mm f/4G ED VR respectively -- much shorter than their predecessors.

Ergonomically arranged switches and buttons enable easy access and comfortable operation even during handheld shooting. These buttons include the Focus Preset function, which instantly recalls a focal point preset with a simple push-button operation; Focus Limiter switch, which restricts AF-servo movement to a controlled shooting distance range; AF-L switch, which makes it possible to lock focus from the lens; and AF-ON, which engages autofocus from the lens. The new A/M focus mode allows instant switching from autofocus to manual focus, even during AF-servo operation. It also offers a major improvement over conventional M/A modes by significantly reducing the possibility of unintentional switching from Auto to Manual. By employing magnesium die-cast in the lens body construction, the new lenses achieved considerable weight savings without sacrificing rugged field-proven construction resistant to both dust and water.
