Notes on auto focus
• In the following cases, it may be difficult to
focus on the subject. If this does happen, use
manual focusing.
- If the subject has no contrast
- If the subject is moving rapidly
- When shooting point light sources, under
street lighting or at night
- When there are very bright objects close to the
subject
- When shooting through a glass window
• If there are a number of objects within the
screen at close and far range, the focus may not
be on the intended subject. In this case, with the
subject on which you want to focus in the center
of the screen, press the PUSH AF button.
• After focusing with the PUSH AF button, if you
operate the zoom or adjust the iris, the depth of
field may become shallower, losing crisp focus.
In such cases, press the PUSH AF button once
more.
• If you focus at wide-angle then zoom to
telephoto, the subject may no longer be in focus.
• It may take time until the image is in focus
while using the slow shutter mode.
Note on zoom speed
Depending on the shooting distance, the zoom
speed may fall as the lens approaches the
telephoto end.
