Manual Focus
Manual focus is available for lenses that do not
sup port autofocus (non-AF Nikkor lens
es) or
when autofocus does not produce the desired
re sults (

mode selector to M and adjust the lens focusing
ring until the image displayed on the clear matte
fi eld in the viewfi nder is in focus. Pho to graphs
can be taken at any time, even when the image
is not in focus.

A-M Selection/Autofocus with Manual Priority
When using a lens that offers A-M selection, select M when focusing manually. With
lenses that support M/A (autofocus with manual priority), focus can be adjusted man-
u al ly with the lens set to M or M/A. See the documentation provided with your lens
for details.
Focal Plane Position
To determine the distance between your subject and
the camera, measure from the focal plane mark on the
camera body. The distance between the lens mounting
fl ange and the focal plane is 46.5 mm (1.83˝).
