The AF-S NIKKOR 300mm f/4E PF ED VR from Nikon is a prime telephoto that features a unique Phase Fresnel element to greatly reduce the size and weight compared to other 300mm lenses. Individual elements also feature both Nano Crystal and Super Integrated Coatings to suppress flare and ghosting, as well as a protective fluorine coating to guard the optical system from dust and moisture. Further contributing to photographing in fast-paced situations and difficult lighting, VR (Vibration Reduction) image stabilization compensates for the effects of camera shake for sharper handheld shooting. Additionally, an electromagnetic aperture mechanism is integrated into the lens design to provide greater exposure control stability that is especially beneficial when working with faster continuous shooting rates.
