Nikon 2181 user manual Major features, Focusing, zooming, and depth Field

Thank you for purchasing the AF-S DX NIKKOR 10-24mm f/3.5-4.5G ED lens. 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- En 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.

■Major features

•This lens employs a Silent Wave Motor to drive the focusing mechanism, making autofocusing smooth,

silent and almost instantaneous. The focus mode switch dis provided for simple selection of

autofocus (A) or manual focus (M) operation.

•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-of- focus.

■Focusing, zooming, and depth of

field

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 (stop- down) button or lever, depth of field can be previewed through the camera viewfinder.

•This lens is equipped with the Internal Focusing (IF) system. As the shooting distance decreases, the focal length also decreases.

•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.
