How to Enable Lens Peripheral Illumination on Your Canon EOS 6D
Some Canon lenses have a problem with illumination falloff in the periphery of the frame. If you’ve ever taken a picture on your EOS 6D and noticed that the edges of the image were dark, you’ve experienced this phenomenon firsthand. The amount of light falloff depends on the lens you’re using.
You can, however, go a long way toward correcting this problem with a camera menu command. This feature is available only for Canon lenses. The peripheral illumination data is stored in the camera’s database. Another problem with lenses is chromatic aberration, which is color fringing around the edges of subjects. You can cure both. To enable lens peripheral illumination:
Press the Menu button.
The previously used menu displays on the camera LCD monitor.
Use the Multi-controller to navigate to the Shooting Settings 2 tab.
Use the Multi-controller or the Quick Control dial to highlight Lens Aberration Correction and then press the Set button.
Note that both problems are corrected by default. Don’t use this command with a third-party lens due to the fact that third-party lenses are not in the camera’s database. If you have a Canon lens attached to the camera and data for the lens is in the camera’s database, this information is noted in the dialog box.
Press the Menu button to exit the menu command.
