User manual NIKON AF 50MM F/1.8D

[. . . ] When mounted on Nikon DXformat 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. [. . . ] 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 three aspherical lens elements and two extra-low dispersion (ED) glass elements, which ensure correction of chromatic aberration. In addition, the rounded aperture produces soft and pleasing blur characteristics in portions of pictures that are out-offocus. Before focusing, rotate the zoom ring 5 to adjust the focal length until the desired composition is framed. If your camera has a depth-of-field preview (stopdown) button or lever, depth of field can be previewed through the camera viewfinder. This lens is equipped with the Internal Focusing (IF) system. The distance scale does not indicate the precise distance between the subject and the camera. Values are approximate and should be used only as a general guide. When shooting distant landscapes, depth of field may influence operation so that the camera may focus at a position that is closer than infinity. 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. Reinforced plastic is used for certain parts of the lens.
