Focus Lock

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. 33) 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).

•  Subjects positioned at some distance in front of or 

behind an object that is also in the focus frame (for 
example, a subject in a cage, where the both the 
subject and the bars of the cage are in the focus 
frame).

•  Subjects dominated by regular geometric patterns, 

such as the windows in an office building.

•  Subjects that contain many fine details, such as a 

field of flowers or other subjects that are small or 
lack variation in brightness.

The camera’s hybrid autofocus system ensures fast focus, particularly when a bright, high-contrast subject is 
positioned in the center of the frame.
