❚❚ 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 99, the in-
focus indicator may sometimes be displayed when the subject is
not in focus; confirm focus in the viewfinder before shooting.
For information on using the electronic rangefinder with
optional AF-S/AF-I teleconverters, see page 423.
A

your subject and the camera, measure
from the focal plane mark (E) on the
camera body (0 1).
The distance
between the lens mounting flange and
the focal plane is 46.5 mm (1.83 in.).
