Vibration reduction technology Silent Wave AF Motor Compatible with FX and DX lenses The Nikon 28-300mm f/3.5-5.6G AF-S VR II IF-ED NIKKOR is a robust, wide to telephoto zoom lens and can cover portraiture, action and architecture images, and as a result is perfect for a roaming photographer with a portable full frame body such as the D700. The versatility of this lens means it can comfortably replace a kit lens and more expansive zoom for a hobbyist, or be a great alternative to several high quality zooms for a professional. And the vibration reduction will keep handshake at bay throughout. The Silent Wave AF motor keeps the focus quick and virtually silent, meaning quieter environments will not be disturbed. Similarly the vibration reduction technology allows for a slower shutter speed to be used without sacrificing sharpness thanks to the elimination of hand shake. The Nikon 28-300mm f/3.5-5.6G AF-S VR II IF-ED NIKKOR can be used on either a DX or FX DSLR although on a DX DSLR the focal length becomes 42-450mm due to the 1.5x magnification level. Autofocus can also be overridden when required by simply twisting the focus ring, rather than needing to switch modes, and autofocus can be re-engaged by releasing it again.
