• The focus lock can be set in any shooting mode.
• When shooting with the focus lock or AF lock using the LCD monitor,
setting the AIAF to Off (p. 76) is recommended since the camera
focuses using the center AF frame only.
• The AF lock is convenient because you can let go of the shutter
button to compose the image. Moreover, the AF lock is still effective
after the picture is taken, allowing you to capture a second image
with the same focus.
• The AF lock can be released by pressing the zoom lever, MENU
button, or by changing the shooting mode or by turning the LCD
monitor off.
