Fast aperture super telephoto lens that is ideal for sports photography. A new optical design delivers crisp, high-contrast images, and features ultra-quiet Autofocus performance, Vibration Reduction II to combat the effect of camera shake at slow shutter speeds, and practical close focusing capabilities. Designed for digital, this lens includes a Nano Crystal coating, ED glass and rounded diaphragm blades to produce images full of detail with excellent out of focus characteristics.

Main Features
 

  • VR II operation realizes the equivalent of a shutter speed four stops faster
     

  • New Tripod mode reduces vibration that may occur at shutter release when shooting with a super-telephoto lens attached to a tripod
     

  • Enhanced optical formulas, engineered to produce exceptional sharpness, contrast and color, render outstanding image integrity
     

  • Three ED (Extra-low dispersion) elements control chromatic aberration while enhancing sharpness and contrast, even at the widest apertures
     

  • Exclusive Nikon Nano Crystal Coat and a Meniscus protective glass element combine to further reduce ghosting and flare for even greater image clarity
     

  • High-performance Nikon Super Integrated Coating realizes superior color reproduction while minimizing ghosting and flare
     

  • Nikon's exclusive Silent Wave Motor enables fast autofocusing with exceptional accuracy and powerful, super-quiet operation
     

  • Rounded diaphragm opening (9 blades) makes out-of-focus elements appear more natural
     

  • Newly added A/M mode reduces the possibility of unintentional switching from Auto to Manual
     

  • Focus Preset function instantly recalls preset focus points with the push of a button
     

  • Engineered to Nikon professional D-SLR standards to effectively resist dust and moisture
     

  • Magnesium die-cast for a lightweight body with rugged construction
     

  • Supplied lens hood effectively minimizes stray light
     

  • Detachable monopod collar provided

MTF (Modulation Transfer Function) is one of the measurements that evaluate a lens' performance; it shows contrast reproducibility of the lens using characteristic spatial frequencies. Spatial frequencies indicate the number of lines per mm.

In the MTF chart of this website, the horizontal axis is in millimeters and shows the distance from the center of the image toward the edges, and contrast value (highest value is 1) is shown in the vertical axis, with fixed spatial frequencies of 10 lines/mm and 30 lines/mm.
The MTF chart for each lens is based on the value at the maximum aperture of the lens; the red line shows the spatial frequency of 10 lines/mm and the blue line, 30 lines/mm.

In the off-axis field, contrast reproducibility of the lens for sagittal direction and meridional direction varies with astigmatic affection. The path of 10 lines/mm indicates the contrast reproducibility of the lens (the higher and straighter is better). The higher and straighter the 30 lines/mm-path is, the higher the resolution of the lens.

Note that the lens performance can not be measured only with MTF chart. Softening or blurring of color also governs measurement.
