Combining long reach and a portable form factor, 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. This element, along with one extra-low dispersion glass element, also helps to greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy. 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.
