Nikon 70-300mm f/4.5 - 5.6G ED-IF AF-S VR (Vibration Reduction) Zoom Nikkor Lens - Refurbished by Nikon U.S.A. Nikon's exclusive VRII technology minimizes the effects of camera shake, allowing photographers to shoot hand-held at as many as 4 shutter speeds slower than would otherwise bepossible, assuring dramatically sharper images in challenging shooting conditions. Normal and Active VR modes are available. Construction features 17 elements in 12 groups with two ED glass elements to minimize chromatic aberration throughout the entire zoom range while ensuring high resolution and contrast. A nine-blade rounded diaphragm opening makes out-of-focus elements appear more natural. The Nikon Silent Wave Motor (SWM) enables fast and quiet autofocusing and smoothswitching between autofocus and manual operation. Two focus modes are available M/A and M. The added compactness and constant lens length provided by an Internal Focus (IF) design means improved handling characteristics and the elimination of the rotation of the front lens element, facilitating the use of circular polarizing filters.
