Nikon D5500 - Manual (Page 269)

245 C The Shooting Menu: Shooting Options
Select On to reduce barrel distortion in photos taken with wide-
angle lenses and to reduce pin-cushion distortion in photos
taken 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.
This item is displayed only with lenses that support it. Selecting
On enables vibration reduction, which takes effect whenever
the shutter-release button is pressed halfway (
0 379). Select Off
to disable vibration reduction.
