Covering a versatile array of wide-angle focal lengths, 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.
