These lenses can be attached to film-based 35mm SLRs, but will not work properly due to the reduced size of the image circle. [. . . ] Getting good results with autofocus Refer to "Notes on using wide or super-wide angle AF Nikkor lenses" on the back of this sheet. Taking flash pictures with cameras having built-in flash When using the following camera, check the focal length and shooting distance before taking flash pictures to prevent vignetting since the light emitted from the flash may be obstructed by the lens barrel. Align the lens hood attachment index ( ) on the lens hood with the hood mounting index on the lens, and turn the hood counterclockwise (as viewed from the camera side) until it click stops. Make sure that the lens hood mounting index aligns with the lens hood setting index ( ). If the lens hood is not correctly attached, vignetting can occur. To facilitate attachment or removal of the hood, hold it by its base rather than its outer edge. While holding down the lens hood lock release button, turn the hood clockwise (as viewed from the camera side) to detach. If the lens mount rubber gasket is damaged, be sure to visit the nearest Nikon authorized dealer or service center for repair. Clean the lens surfaces with a blower brush. To remove dirt and smudges, use a soft, clean cotton cloth or lens tissue moistened with ethanol (alcohol) or lens cleaner. Wipe in a circular motion from center to outer edge, taking care not to leave traces or touch other parts of the lens. Never use thinner or benzene to clean the lens as this might damage it, result in a fire, or cause health problems. [. . . ] When the main subject is a small, patterned subject or scene.
