The AF-S NIKKOR 16-35mm f/4G ED VR from Nikon is a flexible zoom ideal for landscape, cityscape, and interior photography. Its constant f/4 maximum aperture maintains consistent illumination throughout the zoom range and suits working in a variety of lighting conditions. 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. Additionally, this lens also sports a Silent Wave Motor for fast and accurate autofocus along with VR II image stabilization to minimize the appearance of camera shake by 2.5 stops. Wide-angle zoom designed for FX-format sensors, this 16-35mm lens can also be used with DX models where it provides a 24-52.5mm equivalent focal length range. Three aspherical elements are used to reduce spherical aberrations and distortion to realize sharp imagery with accurate rendering. A Nano Crystal Coat has been applied to individual elements to suppress internal reflections, flare, and ghosting for improved contrast and color accuracy when working in strong lighting conditions. 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. VR II (Vibration Reduction) image stabilization helps to minimize the appearance of camera shake by 2.5 stops to benefit shooting handheld in difficult lighting conditions.
