[. . . ] This lens is not compatible with a Nikon F3AF camera when the AF Finder DX-1 is attached. With Nikon autofocus cameras (except the F3AF), first turn the zoom ring until the desired composition is framed in the viewfinder before performing autofocus. For manual focus, focusing is possible at any focal length, but is easier at longer focal lengths, because the image is larger and depth of field is shallower. If your camera has a depth of field preview (stop-down) button or lever, depth of field can be observed while looking through the camera viewfinder. In the following situations, autofocus may not work properly when taking pictures using wide or super-wide angle AF Nikkor lenses. When the main subject in the focus brackets is relatively small. C (see over), when a person standing in front of a distant background is placed within the focus brackets, the background may be in focus, while the subject is out of focus. When the main subject is a small, patterned subject or scene. D (see over), when the subject is highly patterned or of low contrast, such as a field covered with flowers, autofocus may be difficult to obtain. In such situations: (1) Focus on a different subject located at the same distance from the camera, then use the focus lock, recompose, and shoot. Using other camera bodies is not recommended as vignetting occurs. Align the index ( ) on the hood with the lens hood mounting index on the lens, and turn the hood counterclockwise (as viewed from the camera) until it click stops at the index ( ). To facilitate attachment or removal of the hood, hold it by its base rather than its outer edge. To remove dirt and smudges, use a soft, clean cotton cloth or lens tissue moistened with lens cleaner. Wipe in a circular motion from the center outward. Never use thinner or benzene to clean the lens as this might damage the lens, result in a fire, or cause health problems. To protect the front lens element, an NC filter is recommended at all times. A lens hood also helps protect the front of the lens. When storing the lens in the lens case, attach both front and rear caps. When the lens will not be used for a long time, store it in a cool, dry place to prevent mold.
