If the subject is poorly lit, the AF-assist 
illuminator will light automatically to assist 
the autofocus operation when the shutter-
release button is pressed halfway (some 
restrictions apply; 

0 284). Note that the 

illuminator may become hot when used 
multiple times in quick succession and will 
turn off automatically to protect the lamp 
after a period of continuous use. Normal 
function will resume after a brief pause.
