Lens Peripheral Illumination / Chromatic Aberration Correction

Peripheral light fall-off occurs in lenses whose characteristics make the image corners look darker. Color fringing along subject outlines also is a chromatic aberration. Light fall-off and color fringing can be corrected.

The default setting is [Enable] for corrections

Peripheral Illumination Correction

1 Select [Lens aberration correction]. Under the [] tab, select [Lens aberration correction], then press <>. 2 Select the setting. Check that [Correction data available] is displayed for the attached lens. Turn the <> dial to select [Peripheral illumin.], then press <>. Select [Enable], then press <>. If [Correction data not available] is displayed, see “About the Lens Correction Data” 3 Take the picture. The image will be recorded with the peripheral illumination corrected

About the Lens Correction Data

The camera already contains lens peripheral illumination correction data and chromatic aberration correction data for approx. 25 lenses. If you select [Enable], the peripheral illumination correction and chromatic aberration correction will be applied automatically for any lens whose correction data has been registered in the camera.

With EOS Utility (provided software), you can check which lenses have their correction data registered in the camera. You can also register the correction data for unregistered lenses. For details, refer to the Software Instruction Manual (CD-ROM) for EOS Utility

Depending on shooting conditions, noise may appear on the image periphery.

• The correction amount applied will be slightly lower than the maximum correction amount settable with Digital Photo Professional (provided software).

• The higher the ISO speed, the lower the correction amount will be.

Chromatic Aberration Correction

1 Select the setting. Check that [Correction data available] is displayed for the attached lens. Turn the <> dial to select [Chromatic aberration], then press <>. Select [Enable], then press <>. If [Correction data not available] is displayed, see “About the Lens Correction Data” on the next page. 2 Take the picture. The image will be recorded with the chromatic aberration corrected.

If you play back a RAW image shot with the chromatic aberration corrected, the image will be displayed on the camera without the chromatic aberration correction applied. Check the chromatic aberration correction with Digital Photo Professional

Notes for peripheral illumination correction and chromatic aberration correction

About the Lens Correction Data

• Corrections cannot be applied to JPEG images captured when [Disable] was set.

• When using a non-Canon lens, setting the corrections to [Disable] is recommended, even if [Correction data available] is displayed.

• If you use the magnified view during Live View shooting, the peripheral illumination correction and chromatic aberration correction will not be reflected in the image.

• If the effect of the correction is not so visible magnify the image and check it.

• The corrections are also applied when an Extender is attached.

• If the correction data for the attached lens is not registered to the camera, the result will be the same as when the correction is set to [Disable].

• If the lens does not have distance information, the correction amount will be lower.
