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.
• 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.
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.
