Even if the corresponding menu setting is available (not grayed out), setting it to [Off] is recommended. • When peripheral illumination correction is activated: - Depending on the recording conditions, noise may appear in the periphery of the image as a result of the correction. - The level of correction will be lower for lenses that cannot provide distance information. - The level of correction will be lower the higher the ISO speed/gain setting used. - Due to the difference in sensor size, when using EF-S lenses, peripheral illumination fall-off may be more pronounced.

In-Camera Lens Correction
Depending on the characteristics of the lens used, the corners of an image frame may be darker than the center
due to light fall-off (peripheral illumination drop), or color shift/color fringing may be visible along high-contrast
edges in the image (chromatic aberration). If the camera has correction data available for the lens used, it can
apply this correction data to compensate as necessary.
Peripheral illumination correction is available for EF lenses. Chromatic aberration correction is available for EF
lenses and broadcast lenses, including automatic correction for broadcast lenses compatible with L.C.A.C
(
A

that were available at the time the camera went on sale. Correction data for future lenses will be made
available as part of the regular updates released for the camera’s firmware. For more details, visit your local

No peripheral illumination/chromatic aberration correction will be applied in the following cases:

-
When using non-Canon lenses. Even if the corresponding menu setting is available (not grayed out), setting
it to [Off] is recommended.
When peripheral illumination correction is activated:
-
Depending on the recording conditions, noise may appear in the periphery of the image as a result of the
correction.
-
The level of correction will be lower for lenses that cannot provide distance information.
-
The level of correction will be lower the higher the ISO speed/gain setting used.
-
Due to the difference in sensor size, when using EF-S lenses, peripheral illumination fall-off may be more
