Auto Distortion Control G button ➜ C shooting menu Select On to reduce barrel distortion when shooting with wideangle 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 (24×16) as described on page 75; selecting other options may result in heavily cropped photographs or in photographs with severe peripheral distortion.
