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