    Solution

      AF (Auto Focus) can fail to achieve focus (the focus confirmation light blinks) on certain subjects such as the following:

      • Low-contrast subjects. (ex. blue sky, solid-color walls, etc.)
      • Subjects in low light.
      • Extremely backlit reflective subjects. (ex. car with a reflective body)
      • Overlapping near and far objects. (ex. animal in a cage)
      • Repetitive patterns. (ex. Skyscraper windows, computer keyboards, etc.)

      In such cases, do either of the following:
      Focus on an object at the same distance as the subject and lock the focus before recomposing. Please see NOTE below about "focus".
      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".
