Nikon's 18-200mm f/3.5-5.6G ED-IF AF-S DX Zoom-Nikkor is a high-ratio 11x zoom lens with Nikon's exclusive VR II (Vibration Reduction) technology. Nikon's VR II provides the equivalent of a shutter speed 4 steps faster than would otherwise be possible, enabling substantially sharper pictures in challenging conditions. The Nikkor 18-200mm lens incorporates two ED glass and three aspheric lens elements to provide optimal color, contrast and clarity while minimizing chromatic aberrations and other distortion, resulting in outstanding image quality and versatility. In addition, Nikon's compact AF-S Silent Wave Motor provides fast and quiet autofocusing while the M/A mode allows for simultaneous switching between Autofocus and manual focus operation.
