Manual Focus
Manual focus is available for lenses that do not support autofocus (non-AF NIKKOR
lenses) or when the autofocus does not produce the desired results (
0 98).
• AF-S lenses: Set the lens focus mode switch to M.
• AF lenses: Set the lens focus mode switch (if present)
and camera focus-mode selector to M.
• Manual focus lenses: Set the camera focus-mode selector to M.
To focus manually, adjust the lens focus 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.
❚❚The Electronic Rangefinder
If the lens has a maximum aperture of f/5.6 or faster,
the viewfinder focus indicator can be used to confirm
whether the subject in the selected focus point is in
focus (the focus point can be selected from any of the
39 focus points). After positioning the subject in the
selected focus point, press the shutter-release button
halfway and rotate the lens focus ring until the in-focus indicator (
I) is displayed.
Note that with the subjects listed on page 98, the in-focus indicator may sometimes
be displayed when the subject is not in focus; confirm focus in the viewfinder before
shooting.

AF Lenses
Do not use AF lenses with the lens focus mode switch
set to M and the camera focus-mode selector set to AF.
Failure to observe this precaution could damage the
camera or lens.
A
Focal Plane Position
To determine the distance between your subject and the
camera, measure from the focal plane mark (
E) on the
camera body. The distance between the lens mounting
flange and the focal plane is 46.5 mm (1.83 in.).
