[. . . ] Do not handle or touch the camera or lens unit with wet hands. When shooting with back-lighting, do not point the lens at the sun or allow sunlight to pass directly down the lens as this may cause the camera to overheat and possibly cause a fire. When the lens will not be used for an extended period of time, attach both front and rear lens caps and store the lens away from direct sunlight. Failure to do so could result in a fire, as the lens may focus sunlight onto a flammable object. [. . . ] Observe the following precautions when handling the camera and lens Do not look at the sun through the lens or viewfinder Viewing the sun or other strong light sources through the lens or viewfinder could cause permanent visual impairment. DX Nikkor lenses are specially designed for use with Nikon digital-SLR (Nikon DX-format) cameras, such as the D300 and D90. When mounted on Nikon DX-format cameras, the lens picture angle is equivalent to approximately 1. 5× the focal length in 35mm format. Before using this lens, please read these instructions and refer to your camera's User's Manual. This lens employs a Silent Wave Motor to drive the focusing mechanism, making autofocusing smooth, silent and almost instantaneous. More accurate exposure control is possible when this is mounted on a Nikon camera with 3D color matrix metering capability, because subject distance information is transferred from the lens to the camera. Superior optical performance and rendering characteristics are maximized with the use of one aspherical lens element. In addition, soft and pleasing blur characteristics in portions of pictures that are out-of focus are achieved by the rounded diaphragm. Wipe in a circular motion from the center to the outer edge, taking care not to leave traces or touch other parts of the lens. Never use organic solvent such as thinner or benzene to clean the lens, as this could cause damage, result in a fire, or cause health problems. NC filters are available to protect the front lens element. The lens hood also helps to protect the front of the lens. When storing the lens in its flexible lens pouch, attach both the front and rear lens caps. When the lens is mounted on a camera, do not pick up or hold the camera and lens by the lens hood. When the lens will not be used for an extended period of time, store it in a cool, dry place to prevent mold and rust. Be sure to store the lens away from direct sunlight or chemicals such as camphor or naphthalene. Do not get water on the lens or drop it in water as this will cause it to rust and malfunction.
