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 G, E, and D lenses (PC, fisheye, and certain
other lenses excluded); results are not guaranteed with other
lenses. Before using auto distortion control with DX lenses, select
On for Auto DX crop or choose an image area of DX (24Ч16) 1.5Ч
(
0 86); selecting other options may result in heavily cropped
photographs or in photographs with severe peripheral distortion.
