Pre-AF
If On is selected when Multi AF or Spot AF is selected for
Focus (page 59), the camera will continue to focus even
when the shutter-release button is not pressed halfway
(the focus range, however, is narrower than for normal fo-
cus). This may decrease the time needed to focus when a
picture is taken, potentially improving shutter response.
