The Electronic Rangefinder
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
51 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 72, the in-
focus indicator may sometimes be displayed when the subject is not in focus; confirm
focus in the viewfinder before shooting.

AF Lenses That Are Not AF-S Lenses
Except when using an AF-S lens, 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.).
