To Release the AF Lock:
Press the _ button.
• When shooting with the focus lock or AF lock using the LCD
monitor, setting [AF Frame] to [Center] (p. 82) makes
shooting easier since the camera focuses using the center
AF frame only.
• AF frames do not display in _,_, mode.
• Try to shoot as close to the glass as possible to reduce the
chances of light reflecting back off the glass when you shoot
a subject through glass.
