Nikon 28-70mm f/2.8D ED-IF AF-S Zoom Nikkor Lens for Nikon Digital SLR Camera. They push the leading edge of lens-making in their effort to provide the "glass" that makes the world's greatest pictures.

AF Nikkor lenses work with Nikon SLRs for optimal performance, even the very latest. The Nikon 28-70mm f2.8D ED-IF Autofocus Zoom Nikkor Lens is a wide to telephoto 2.5x zoom lens ideal for architecture and portraiture.

The ED glass element reduces chromatic aberrations providing superior optical performance--even at maximum aperture. There is no power drain when manually focusing for optimum battery use. The molded-glass aspherical lens minimizes distortion for higher resolution and superior contrast. The lens holds a fast and constant f2.8 maximum aperture through the entire focal range, while the M/A mode provides quick switching between autofocus and manual focus operation. The nine-blade rounded diaphragm opening makes out-of-focus elements appear more natural. ED glass: An essential element of Nikkor telephoto lenses Nikon developed ED (Extra-low Dispersion) glass to enable the production of lenses that offer superior sharpness and color correction by minimizing chromatic aberration. Put simply, chromatic aberration is a type of image and color dispersion that occurs when light rays of varying wavelengths pass through optical glass. In the past, correcting this problem for telephoto lenses required special optical elements that offer anomalous dispersion characteristics--specifically calcium fluoride crystals. However, fluorite easily cracks and is sensitive to temperature changes that can adversely affect focusing by altering the lens' refractive index. So Nikon designers and engineers put their heads together and came up with ED glass, which offers all the benefits and none of the drawbacks of calcium fluorite-based glass. With this innovation, Nikon developed several types of ED glass suitable for various lenses. They deliver stunning sharpness and contrast even at their largest apertures. In this way, Nikkor's ED-series lenses exemplify Nikon's preeminence in lens innovation and performance. Nikon Super Integrated Coating ensures exceptional performance To enhance the performance of its optical lens elements, Nikon employs an exclusive multilayer lens coating that helps reduce ghost and flare to a negligible level. Nikon Super Integrated Coating achieves a number of objectives, including minimized reflection in the wider wavelength range and superior color balance and reproduction. Nikon Super Integrated Coating is especially effective for lenses with a large number of elements, like our Zoom-Nikkors.

Also, Nikon's multilayer coating process is tailored to the design of each particular lens. The number of coatings applied to each lens element is carefully calculated to match the lens type and glass used, and also to assure the uniform color balance that characterizes Nikkor lenses.

This results in lenses that meet much higher standards than the rest of the industry. Aspherical lens elements Nikon introduced the first photographic lens with aspherical lens elements in 1968. Aspherical lenses virtually eliminate the problem of coma and other types of lens aberration-- even when used at the widest aperture.

They are particularly useful in correcting the distortion in wide-angle lenses. In addition, use of aspherical lenses contributes to a lighter and smaller lens design. Nikon employs three types of aspherical lens elements. Precision-ground aspherical lens elements are the finest expression of lens-crafting art, demanding extremely rigorous production standards. Hybrid lenses are made of a special plastic molded onto optical glass.

Molded glass aspherical lenses are manufactured by molding a unique type of optical glass using a special metal die technique. Internal Focusing Imagine being able to focus a lens without it changing in size. Nikon's IF technology enables just that.

All internal optical movement is limited to the interior of the non-extending lens barrel. This allows for a more compact, lightweight construction as well as a closer focusing distance. In addition, a smaller and lighter focusing lens group is employed to ensure faster focusing.

The IF system is featured in most Nikkor telephoto and selected Nikkor zoom lenses. Distance information D-type and G-type Nikkors relay subject-to-camera distance information to AF Nikon camera bodies. This then makes possible advances like 3D Matrix Metering and 3D Multi-Sensor Balanced Fill-Flash. Note: D-type and G-type Nikkors provide distance information to the following cameras: Auto exposure; F6, F5, F100, F90X, F80, F75, F70, F65, F60, F55, F50, Pronea S, Pronea 600i, D2 series, D1 series, D100 and D70s/D70.

Flash control; F6, F5, F100, F90X, F80, F75, F70, D2 series, D1 series, D100 and D70s/D70. Silent Wave Motor Nikon's AF-S technology is yet another reason professional photographers like Nikkor telephoto lenses. AF-S Nikkors feature Nikon's SWM which converts "traveling waves" into rotational energy to focus the optics. This enables high-speed autofocusing that's extremely accurate and super quiet. M/A mode AF-S Nikkors feature Nikon's exclusive M/A mode, that allows switching from autofocus to manual operation with virtually no time lag--even during AF servo operation and regardless of AF mode in use.
