Manual Focus Manual focus is available for lenses that do not support autofocus (non-AF Nikkor lenses) or when autofocus does not produce the desired results (pg. 55). To use manual focus, set the camera focus-mode selector and/or the lens focus-mode switch as follows: • AF-S lenses: Set the lens focus-mode switch to M. h • AF lenses: Set the both the camera focus-mode selector and the lens focus-mode switch to M. • Manual focus lenses: Set the camera focus-mode switch to M. Focus-mode selector To focus manually, adjust the lens focusing ring until the image displayed on the clear matte field in the viewfinder is in focus. Photographs can be taken at any time, even when the image is not in focus. D Using Manual Focus with AF Lenses Be sure the camera focus-mode selector is set to M when using manual focus with AF lenses. Focusing manually with the focus-mode selector set to AF could damage the lens.
