1033 Lens Peripheral Illumination CorrectionThe camera already contains lens peripheral illumination correctiondata for about 25 lenses. In step 2, if you select [Enable], the peripherallight correction will be applied automatically for any lens whosecorrection data has been registered in the camera.With EOS Utility (provided software), you can check which lenses havetheir correction data registered in the camera. You can also register thecorrection data for unregistered lenses. For details, see the SoftwareInstruction Manual (CD-ROM) for EOS Utility.About the Lens Correction Data For JPEG images already captured, lens peripheral illuminationcorrection cannot be applied. Depending on shooting conditions, noise might appear on the imageperiphery. When using a non-Canon lens, setting the correc ion to [Disable] isrecommended, even if [Correction data available] is displayed. Lens peripheral light correction is applied even when an Extender isattached. If he correction data for the attached lens has not been registered to thecamera, the result will be the same as when the correc ion is set to[Disable]. The correction amount applied will be slightly lower than the maximumcorrection amount settable with Digital Photo Professional (providedsoftware). If the lens does not have distance information, the correction amount willbe lower. The higher the ISO speed, the lower the correction amount will be.
