نقل قول:
The new 400mm f/2.8 super-telephoto lens delivers upon the NIKKOR promise of uncompromising performance, thanks to overall enhancements to the optical characteristics of the lens, which go beyond simply enhancing image quality. With a refined optical formula, those who shoot fast action sports from a distance or rapidly moving wildlife will appreciate the improved autofocus (AF), exposure accuracy and speed. The lens now contains two fluorite elements that, together with two Extra-Low Dispersion (ED) glass elements and Nano Crystal Coat, helps ensure outstanding performance with minimal chromatic aberration and flaring. The internal construction of the lens comprises 16 elements in 12 groups, and features an electromagnetic diaphragm, similar to that employed in the AF-S NIKKOR 800mm f/5.6 lens. Denoted by the “E” designation, this feature allows for stable exposures during high speed shooting, such as the 11 frames-per-second (fps) possible with the Nikon D4S HD-SLR. Additionally, the lens employs a nine-blade rounded diaphragm that creates a circular, natural looking out of focus area – a requirement for action and wildlife shooters who need clear separation between the subject and the background.
The refined construction of this lens has additional benefits, creating a beautifully balanced instrument for professionals that is nearly two full pounds (816 grams) lighter than its predecessor, tempting the user to shoot handheld when needed. Whether trackside or courtside, photographers will value Nikon’s Vibration Reduction (VR) technology with up to four stops of image stabilization*, and the addition of the new VR Sport Mode. When shooting action, especially on a monopod, the VR Sport Mode recognizes a panning motion to provide accurate compensation for camera shake, resulting in super-sharp images, with motion blur where the photographer intended. For working in challenging environments, the lens features a protective front meniscus element with a fluorine coating, which resists dirt and moisture on the front of the lens. Other pro-minded features include the addition of a rotating tripod collar for seamless switching between compositions, and buttons on the lens barrel compatible with the new AF functions of the Nikon D4S.
