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 against 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 which is especially beneficial when working with faster continuous shooting rates. One Phase Fresnel element and one extra-low dispersion lens element work to greatly reduce chromatic aberrations and color fringing; improve overall image sharpness, clarity, and color fidelity; and help to minimize the overall weight of the lens. Vibration Reduction Image stabilization helps to reduce the appearance of camera shake by 4.5 stops, benefiting this lens's use in low-light conditions. Additionally, a designated Sport Mode is well-suited to working in fast-paced conditions and a Tripod Mode helps to suppress subtle ground vibrations when working atop a support system. An internal focusing design is also used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds. The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
