Correction of Lens Aberrations due to Optical Characteristics
Lens Correction Data
The lens correction data for lens aberration corrections is registered
(stored) in the camera. With [
Enable ] selected, the peripheral illumination
correction, distortion correction, Digital Lens Optimizer, chromatic aberration
correction, and diraction correction will be applied automatically.
For lenses incorporating the correction data, it is not necessary to
register the correction data to the camera.
General Cautions for Lens Aberration Correction
o
Peripheral illumination correction, chromatic aberration correction,
distortion correction, and diraction 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 diraction correction) if the
lens used does not have distance information.
General Notes for Lens Aberration Correction
o
The eect of the lens aberration correction varies depending on the lens
used and shooting conditions. Also, the eect may be dicult to discern
depending on the lens used, shooting conditions, etc.
o
If the correction is di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 diraction correction).
o
If necessary, refer to the EOS Utility Instruction Manual as well.
