The Nikon AF-S DX NIKKOR 18-200 mm. f/3.5-5.6G ED VRII Zoom Lens is a great one-lens solution for DX-format D-SLRs. Its wide angle to telephoto focal range gives photographers a versatile tool to get the shot without having to switch lenses. It is engineered with superior quality ED (Extra-low Dispersion) elements yielding sharpness & color correction without distortion, even at wide apertures. in addition, this zoom is constructed with a 7-blade diaphragm which renders captured images with natural-looking out-of-focus elements.
