❚❚ The Electronic Rangefinder (Viewfinder Photography)
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 in "Getting Good
Results with Autofocus" (0 114), 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 "AF-S/AF-I Teleconverters" (0 281).
A
AF-P Lenses
When an AF-P lens (0 279) is used in manual focus mode, the in-focus
indicator will flash in the viewfinder (or in live view, the focus point will
flash in the monitor) to warn that continuing to rotate the focus ring in
the current direction will not bring the subject into focus.
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.).
