This zoom lens was exclusively designed for use with Nikon digital Single-Lens Reflex (SLR) cameras and has a 6.9:1 zoom ratio. The image circle is designed to match the size of the image sensor of digital SLR cameras. From wide angle to telephoto, this new zoom lens can capture a wide range of subjects. As there is no need to change lenses, there is no risk of missing those great shots. This lens has a minimum focusing distance of 50cm (19.6") at all focal lengths and a maximum magnification of 1:5.3. A distance scale on the focus ring makes the lens convenient and easy to use. A Special Low Dispersion (SLD) lens and two aspherical glass elements produce a high level of optical performance through the entire zoom range, and Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras.
