• Chromatic aberration correction (p.211)
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 (p.448).
• Diffraction correction (p.212)
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 (p.448).
Processing RAW images in the camera will not produce exactly the
same results as processing RAW images with Digital Photo Professional
(EOS software).
If you perform [ Brightness adjustment ], noise, banding, etc. may be
intensified with the effects of adjustment.
When [ Digital Lens Optimizer ] is set, noise may be intensified with the
effects of correction. Also, depending on the shooting conditions,
stronger application of outline emphasis may result. If necessary, adjust
the Picture Style’s Sharpness.
When processing images with [ Distortion correction ] set to [ Enable ],
AF point display information (p.402) or Dust Delete Data (p.460) will not
be appended to the image.
The lens correction data for lens aberration corrections is registered
(stored) in the camera.
The effect of the lens aberration correction varies depending on the lens
used and shooting conditions. Also, the effect may be difficult to discern
depending on the lens used, shooting conditions, etc.
See page 211 regarding the correction data for Digital Lens Optimizer.
