Manual Focus
Manual focus can be used when autofocus is not available or does not produce the
desired results (0 52).
1 Set the lens focus-mode switch.
If the lens is equipped with an A-M, M/A-M, or A/M-M
mode switch, slide the switch to M.
2 Focus.
To focus manually, adjust the lens focus ring until the
image displayed on the clear matte field in the viewfinder
is in focus.
Photographs can be taken at any time, even
when the image is not in focus.
❚❚ 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 39 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 52, the in-focus indicator may sometimes be displayed when the subject is not
in focus; confirm focus in the viewfinder before shooting.
