~ Continuous-servo Autofocus
In AF-C mode or when continuous-servo autofocus is selected in AF-A mode, the camera gives
priority to shutter response and the shutter may be released before the in-focus indicator is
displayed.
B Getting Good Results with Autofocus
Autofocus does not perform well under the conditions listed below. The shutter release may
be disabled
if the camera is unable to focus under these conditions, or the in-focus indicator
(e) may be displayed and the camera may sound a beep, allowing the shutter to be released
even
when the subject is not in focus. In these cases, focus manually (U 60) or use focus lock
(:.::..J 58) to focus on another subject at the same distance and then recompose the
photograph.

~ The AF-Assist Illuminator
If the subject is poorly lit, the AF-assist illuminator will light AF-assist illuminator
automatically to assist the autofocus operation when the shutter-
release
button is pressed halfway. The AF-assist illuminator will not
light during continuous-servo autofocus or manual focus, in
shooting modes in which the AF-assist illuminator can not be used,
or if Off has been selected for Custom Setting a2 (Built-in AF-assist
illuminator;
------1155). The illuminator has a range of about 0.5-3.0

(1 ft. 8 in.-9 ft. lOin.); when using the illuminator, use a lens with
a focal length of 18-200 mm and remove the lens hood.
