Solution
AF (Auto Focus) can fail to achieve focus (the focus confirmation light blinks) on certain subjects such as the following:
- Very low-contrast subjects (Example: Blue sky, solid-color walls, etc.)
- Subjects in very low light
- Extremely backlit or reflective subjects (Example: Car with a highly reflective body, etc.)
- Overlapping near and far objects. (Example: Animal in a cage, etc.)
- Repetitive patterns (Example: Skyscraper windows, computer keyboards, etc.)
In such cases, do one of the following:
- Focus on an object at the same distance as the subject and lock the focus before recomposing (For information on the focus lock, please refer to the following note and the Related information section).
- Set the lens focus mode switch to < MF > and focus manually.
NOTE
With [One-Shot AF], while you press the shutter button halfway to focus a still subject, the focus will be locked. You can then recompose the shot and press the shutter button completely to take the picture. This is called "focus lock".
