When Autofocus Fails Autofocus can fail to achieve focus (the focus confirmation light blinks) with certain subjects such as the following: Subjects difficult to focus 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.) Near and far subjects covered by an AF point (Example: Animal in a cage, etc.) Repetitive patterns (Example: Skyscraper windows, computer keyboards, etc.) In such cases, do one of the following: (1) With One-Shot AF, focus an object at the same distance as the subject and lock the focus before recomposing (p.56). (2) Set the lens focus mode switch to and focus manually. MF: Manual Focusing 1 Set the lens focus mode switch to . X will be displayed on the LCD panel. Focusing ring 2 Focus the subject. Focus by turning the lens focusing ring until the subject looks sharp in the viewfinder. If you press the shutter button halfway during manual focusing, the AF point which achieved focus will flash briefly in red and the focus confirmation light will light in the viewfinder. 80
