The AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED Telephoto Zoom Lens from Nikon is a high-performance 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 (equivalent 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. 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. Silent Wave Motor SWM (Silent Wave Motor) enables quiet automatic focusing with quick and convenient switching between autofocus and manual operation. Internal Focusing IF (Internal Focusing) design for fixed lens length and non-rotating front element allows the use of circular polarizing filters and lens-mounted flash accessories. Nikon VR II (Vibration Reduction) Image Stabilization Vibration Reduction, engineered specifically for each VR NIKKOR lens, enables handheld shooting at up to 4 shutter speeds slower than would otherwise be possible, assuring dramatically sharper still images and video capture. ED Glass Two ED glass elements minimize chromatic aberration across the entire zoom range while ensuring high resolution and contrast. Rounded Diaphragm 9-blade rounded diaphragm makes out-of-focus elements blend together smoothly for natural-looking backgrounds.
