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
falloff can be corrected. By default, Peripheral illumination and
Chromatic aberration correction are set to [
Enable
], and Distortion
correction is set to [
Disable
].

Depending on shooting conditions, noise may appear on the image periphery.
The correction amount applied will be lower than the maximum correction amount
that can be applied with Digital Photo Professional (EOS software, p.512).
The higher the ISO speed, the lower the correction amount will be.
In Basic Zone modes, the peripheral illumination correction and
chromatic aberration correction will be applied automatically. Distortion
correction will not be applied.
