Autofocus
Although the camera boasts a high-precision autofocus system, it may be unable to focus on the subjects
listed below. If the camera is unable to focus using autofocus, use focus lock (pg. 19) to focus on another
subject at the same distance and then recompose the photograph.
• Very shiny subjects such as mirrors or car bodies.
• Fast-moving subjects.
• Subjects photographed through a window or other reflective object.
• Dark subjects and subjects that absorb rather than reflect light, such as hair or fur.
• Insubstantial subjects, such as smoke or flame.
• Subjects that show little contrast with the background (for example, subjects in clothing that is the same
color as the background).
• Subjects positioned in front of or behind a high-contrast object that is also in the focus frame (for example, a
subject photographed against a backdrop of highly contrasting elements).
