The Nikon AF-S VR 70-300mm f/4.5-5.6G IF-ED is a high-performance super telephoto zoom lens that has been designed to meet the demands of both digital and 35mm format SLR users. It offers a 4.3x zoom with a range of 70-300mm (105-450mm on a DX Nikon D-SLR) and features ED (Extra-low Dispersion) glass elements that ensure superior optical performance. This lens incorporates Nikon’s second-generation vibration reduction system (VR II) that allows flexible hand-held shooting by stabilizing the image to the equivalent extent of using a shutter speed that is four stops faster when compared with a conventional lens (as determined by Nikon performance test). The SWM (Silent Wave Motor) and IF (Internal Focusing) ensure fast and quiet focusing action, and the nine-blade rounded diaphragm makes out-of-focus elements blend smoothly to produce natural-looking, harmonious backgrounds.
