This high-performance super telephoto zoom lens offers a 4.3x zoom with a range of 70-300mm f/4.5-5.6 (105-450mm on a DX Nikon D-SLR) and features extra-low dispersions glass elements to ensure superior optical performance. The lens also features Nikon's vibration reduction system which will reduce any hand-held or mechanical vibrations. 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. Suitable for use with Nikon Digital SLR cameras.
