Used to reduce aberrations and enable a more compact lens size. Aspherical lenses minimize coma and other types of lens aberrations, even when used at the widest aperture. They are particularly useful in correcting distortion in wide-angle lenses and help contribute to a lighter, more compact design by reducing the number of standard (spherical) elements necessary. Aspherical lens elements correct these distortions by continuously changing the refractive index from the center of the lens. <span class="a-text-bold">ED (Extra-Low Dispersion) Glass</span> - An optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations. <span class="a-text-bold">Electromagnetic Diaphragm Mechanism -</span> An electromagnetic diaphragm mechanism in the lens barrel provides highly accurate electronic diaphragm or aperture blade control when using auto exposure during continuous shooting. With conventional D/G type lenses, the diaphragm blades are operated by mechanical linkage levers. <span class="a-text-bold">HRI</span> - HRI stands for High Refractive Index Lens. With a refractive index of more than 2.0, one HRI lens can offer effects equivalent to those obtained with several normal glass elements and can compensate for both field curvature and spherical aberrations. Therefore, HRI lenses achieve great optical performance in an even more compact body. <span class="a-text-bold">IF Lens</span> - A NIKKOR lens in which only the internal lens group shifts during focusing. Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances. These lenses will be designated with the abbreviation IF on the lens barrel. <span class="a-text-bold">M/A</span> - Select NIKKOR lenses have a focusing mode which allows switching from automatic to manual focusing with virtually no lag time by simply turning the focusing ring on the lens. This makes it possible to seamlessly switch to fine manual focusing while looking through the viewfinder. <span class="a-text-bold">Nano Crystal Coat</span> - An anti-reflective coating developed by Nikon that virtually eliminates internal lens element reflections across a wide range of wavelengths. Nano Crystal Coat solves ghost effects caused by red light and effectively reduces ghost and flare caused by light entering the lens diagonally. <span class="a-text-bold">Silent Wave Motor</span> - AF-S NIKKOR lenses feature Nikon&#039;s Silent Wave Motor (SWM), which represents a significant advance in AF lens technology. SWM uses ultrasonic vibrations-rather than a gear system-to focus the lens, providing incredibly smooth, silent and precise autofocus operation. <span class="a-text-bold">Super Integrated Coating</span> - Nikon Super Integrated Coating is Nikon&#039;s term for its multilayer coating of the optical elements in NIKKOR lenses. <span class="a-text-bold">Vibration Reduction</span> - A Nikon in-lens technology that improves image stability by automatically compensating for camera shake. Lenses that offer VR will feature the abbreviation VR on the lens barrel. <span class="a-text-bold">Focal Length Range</span> 24 - 70mm <span class="a-text-bold">Maximum Aperture </span>f/ 2.8 <span class="a-text-bold">Format</span> FX/35mm <span class="a-text-bold">Lens Elements</span> - 20 <span class="a-text-bold">Lens Groups</span> - 16 <span class="a-text-bold">VR (Vibration Reduction) Image Stabilization</span> Yes <span class="a-text-bold">Nano Crystal Coat</span> Yes <span class="a-text-bold">AF-S (Silent Wave Motor) </span>Yes <span class="a-text-bold">Filter Size</span> - 82mm <span class="a-text-bold">Approx.
