The AF-S NIKKOR 14-24mm f/2.8G ED presents a flexible ultra-wide-angle range of focal lengths, well-suited for landscape, nature, and interior photography. This lens is characterized by its f/2.8 constant maximum aperture, which affords consistent performance and illumination throughout the zoom range. This 14-24mm lens can also be used with DX models where it provides a 21-36mm equivalent focal length range. The optical design contains three aspherical elements and two extra-low dispersion elements, which greatly reduce distortion and aberrations for a high degree of sharpness, clarity, and accurate rendering. A Nano Crystal Coat has also been applied to control flare and ghosting for greater contrast and color accuracy in harsh lighting and backlit conditions. Built-in petal-shaped lens hood helps to prevent stray light from causing flare and also offers some protection to the front lens element. Rounded nine-blade diaphragm promotes a pleasing out of focus quality that benefits the use of shallow depth of field techniques.
