❚❚ 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 11 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 76, the in-focus
indicator may sometimes be displayed when the subject is not in
focus; confirm focus in the viewfinder before shooting.
A
Selecting Manual Focus with the Camera
If the lens supports M/A (autofocus with
manual override) or A/M (autofocus with
manual override/AF priority), manual focus
can also be selected by setting the camera
focus mode to MF (manual focus; 0 74).
Focus can then be adjusted manually,
regardless of the mode selected with the
lens.
