Focus-Aid Operation (Using the Focus
With the AF-Nikkor's A-M switch (@ set at M, or with other Nikkor
or Nikon Series E lenses having a maximum aperture of f/3.5 or
faster (as listed on page 20), you can use the focus indicators
as a guide as you rotate the lens focusing ring. First, center the
main subject (if possible, a subject's vertical line) within the
focusing frame: then depress the shutter release button halfway
to make the red arrows light up (focus information stays on for
16 sec. after removing your finger). If only the far-focus arrow
(◄ ) lights up, this indicates that the lens is focused behind the
subject, whereas the near-focus arrow (► ) indicates that the
lens is focused in front of the subject. These red arrows are very
convenient, because they tell you in which direction to turn the
focusing ring: just turn in the direction of the arrow. When the
image is in focus, both red arrows light up continuously.
When there is a big difference between the actual camera-to-
subject distance and distance set on the lens, the focus-
impossible warning appears. In this case, turn the focusing ring
until one of the red arrows lights up: then continue to turn the
Indicators)
ring until both arrows are lit, indicating sharp focus. If only the
far-focus arrow (◄ ) remains lit after the ring has been rotated
fully counterclockwise, this means the subject is closer than the
closest focusing distance of the lens. If the subject is much
closer than the closest focusing distance of the lens, the red X
will light up continuously.
In case the red X blinks or lights up continuously and does not
disappear even after the focusing ring is turned, this indicates
that the focus-aid indication system does not function well with
the particular subject or shooting situation (please refer to page
26 for further details).
Note:
While shooting last-moving subjects, one or both of the red arrows
may biink to show that the image is quite dose to the in-focus zone: for
ordinary snapshots, taking the shot even in this situation can produce
satisfactory results. However, if sharp focus is mandatory, continue to
rotate the focusing ring until both red arrows light up continuousiy.
