Tamron Auto Focus 70-300mm f/4.0-5.6 Di LD Macro Zoom Lens with Built In Motor for Nikon Digital SLR (Model A17NII)

From the Manufacturer Designed for optimum handling ease and portability (it weighs only 458g <16.2oz.> ), it’s ideal for handheld shooting with full-frame and APS-C format SLRs. Its unsurpassed close-focusing ability (down to 0.95m (3.1 feet ) or 1:2 in macro mode) makes it perfect for nature and portrait photography. AF 70-300mm f/4.0-5.6 Di LD Macro Zoom Lens Features Low Dispersion (LD) Glass for Greater Lens Sharpness Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely low dispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)"
