Peripheral light fall-off is a phenomenon that makes the image corners
look darker due to the lens characteristics. Color fringing along subject
outlines is called chromatic aberration. And image distortion due to lens
characteristics is called distortion. These lens aberrations and light fall-
off can be corrected. By default, Peripheral illumination and Chromatic
aberration correction are set to [Enable], and Distortion correction is set
If [Cannot correct - no data] is displayed, see “Lens Correction Data”

The correction amount applied will be lower than the maximum
correction amount settable with Digital Photo Professional (EOS
The higher the ISO speed, the lower the correction amount will be.
