shutter release button is depressed halfway, your
subject is in sharp focus even if you move the
camera to the left or right.
• The focus lock is released if you remove your
finger from the shutter release button.

The camera's auto-focus mechanism may not be able to
focus properly on the following kinds of subjects. In such

focus on another object located at an equivalent
distance from the camera as the desired subject, then
return the camera to the original position and take the
picture.

• Subjects characterized by a recurring pattern.
• Very dark subjects.
• Subjects composed primarily of horizontal stripes
• Extremely bright or glossy subjects.

or very near the focusing frame, or when the sun or
other bright light source is visible inside the viewfinder.
• Scenes in which two objects visible inside the focusing
frame are located at greatly differing distances.
