Shooting Hard-to-Focus Subjects (Focus Lock, AF Lock)
*The AF lock only works in the 
 or 
 mode.
It may be difficult to focus on the following types of subjects. Use the focus 
lock or AF lock in these situations.
• Subjects with extremely low contrast to the surroundings
• Subjects with extremely bright objects at the center of the composition
• Subjects that are moving quickly
• Subjects through glass: 
Try to shoot as close to the glass as possible to reduce the chances of 
light reflecting back off the glass.
• Subjects with horizontal stripes 
Shooting with the Focus Lock
1
Aim the camera so that an object at 
the same focal distance as the main 
subject is centered in the 
viewfinder or in the AF frame 
displayed on the LCD monitor.
2
Press the shutter button halfway 
(two beeps will play).
The focal distance to the object is locked.
3
Re-aim the camera to compose the 
shot as desired and press the 
shutter button fully.
