Peripheral Illumination Correction

The EOS 5D Mark II and EOS 50D DSLRs feature a new Menu setting called Peripheral illumination correction. This is used to automatically adjust the images shot on the camera to correct for corner shading, sometimes wrongly identified as vignetting, so the brightness is more even across the scene. With a lens attached to the camera, select the Peripheral illumin. correct. setting from the menu. The camera will tell you if data is available for the lens you have attached and you can select to Enable or Disable the setting.
