Lens Aberration Correction
General Cautions for Lens Aberration Correction
z
Peripheral illumination correction, chromatic aberration correction, distortion
correction, and diffraction correction cannot be applied to JPEG images already
taken.
z
When using a non-Canon lens, setting the corrections to [Disable] is
recommended even if [Correction data available] is displayed.
z
Magnifying the periphery of the image may display parts of the image that will
not be recorded.
z
The correction amount will be less (except for diffraction correction) if the lens
used does not have distance information.
General Notes for Lens Aberration Correction
z
The effect of the lens aberration correction varies depending on the lens used
and shooting conditions. Also, the effect may be difcult to discern depending
on the lens used, shooting conditions, etc.
z
If the correction is difcult to discern, magnifying and checking the image after
shooting is recommended.
z
Corrections can be applied even when an extender or life-size converter is
attached.
z
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] (except for
diffraction correction).
z
If necessary, refer to the EOS Utility Instruction Manual as well.
