The Shooting Menu: Shooting Options
Select On to reduce barrel distortion when shooting with wide-
angle lenses and to reduce pin-cushion distortion when 
shooting with long lenses (note that the edges of the area visible 
in the viewfinder may be cropped out of the final photograph, 
and that the time needed to process photographs before 
recording begins may increase). This option does not apply to 
movies and is available only with type E and G lenses (fisheye, 
and certain other lenses excluded); results are not guaranteed 
with other lenses.
Choose whether the built-in AF-assist 
illuminator lights to assist the focus 
operation when lighting is poor.
