Lens aberr correction
• Peripheral illum corr ( )
A phenomenon that makes the image corners look darker due to the lens
characteristics can be corrected. If [Enable] is set, the corrected image will be
displayed. If the effect is difficult to discern, magnify the image ( ) and check the
four corners. The peripheral illumination correction applied with the camera will be
less pronounced than that applied with the Digital Photo Professional (EOS
software) at maximum correction amount. If the effects of correction are not
apparent, use Digital Photo Professional to apply the peripheral illumination
correction.
• Distortion correction ( )
Image distortion due to lens characteristics can be corrected. If [Enable] is set, the
corrected image will be displayed. The image periphery will be trimmed in the
corrected image.
Since the image resolution may look slightly lower, adjust the sharpness with the
Picture Style's [Sharpness] parameter setting as necessary.
• Digital Lens Optimizer ( )
Correct lens aberration, diffraction, and low-pass filter-induced loss of sharpness by
applying optical design values. Selecting [Enable] corrects both chromatic
aberration and diffraction, although these options are not displayed.
• Chromatic aberr corr ( )
Chromatic aberrations (color fringing along the subject's outline) due to the lens
characteristics can be corrected. If [Enable] is set, the corrected image will be
displayed. If the effect is difficult to discern, magnify the image ( ).
• Diffraction correction ( )
The diffraction by the lens aperture degrading the image sharpness can be
corrected. If [Enable] is set, the corrected image will be displayed. If the effect is
difficult to discern, magnify the image ( ).
