The superior functioning of the newly developed
optical system ensures flawless synchronization with Nikon’s digital
SLRs. The new optical design features three ED (Extra-low Dispersion)
glass elements that minimize chromatic aberration, producing
consistently high-quality images. Nano Crystal Coat, extra-low
refractive index coating, 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 occur when light reflected
from a digital camera’s image sensor is in turn reflected off an
ordinary flat protective glass element.
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. (400mm f/2.8G), 4.0 m/13.1 ft. (500mm f/4G) and 5.0 m/16.4 ft.
(600mm f/4G) respectively (at AF) — much shorter than their
Ergonomically arranged switches and buttons
enable easy access and comfortable operation even during handheld
shooting. The Focus Preset function instantly recalls a focal point
preset with a simple pushbutton operation; the Focus Limiter switch
restricts AF-servo movement to a controlled shooting distance range;
the AF-L switch makes it possible to lock focus from the lens; and
AF-ON engages autofocus from the lens.
The new A/M focus mode allows instant switching
from autofocus to manual focus, even during AF servo operation, and
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, we achieved considerable weight savings without
sacrificing rugged field-proven construction resistant to both dust and
With their unprecedented image quality,
responsiveness and versatility, these new NIKKORs are certain to set a
new benchmark for super-telephoto lenses.
