When Auto Focus Fails
The Auto Focus function requires contrast on the subject. Auto Focusing may fail to
achieve accurate focus with certain subjects described below. In such cases, either
switch to the manual focus mode and focus manually, or bring into focus an object at
the same distance as the object you want to photograph, lock the focus using the
focus lock mechanism, then take the picture. (see the following page)
Low-contrast subject (blue
skies, white walls and other
objects)
Two or more objects overlap at
different distances within the
focus frame
(animals in
cages, etc.)
Subjects with continuous
repeated patterns (building
exteriors, blinds, etc.)
Extremely backlit reflective
subjects (car bodies, water
surfaces, etc.)
When the subject is far smaller than the focus frame
2. Lock the focus.
When the focus mark in the viewfinder LCD
is lit, press the AF lock button on the front of the
camera to lock the focus.
When the focus mode is set at “S” (single
focus mode) and the focus mark is lit,
hold the shutter release button halfway down
to lock the focus.
Using the Focus Lock Function
3. Adjust the composition.
With the shutter release button half-pressed,
slide the camera to achieve the desired
composition, and release the shutter.
1. Set the focus mode selector
lever to “S” or “C.”
Put the subject in the focus frame and half-
press the shutter release button.
If the object that you want to focus on is not in the focus frame , the camera
focuses on the background at the center. In such cases use the focus lock function to
lock the focus before releasing the shutter.
1. Assignment of the AEL and AFL buttons can be swapped.
Custom settings (C-09 on page 85).
2. You can set the camera so that when the AFL button is pressed, AF is activated
and AF lock is performed
