Description

Lens Aberration Correction

Solution

 

Lens Aberration Correction

Vignetting, image distortion, and other issues may be caused by lens optical characteristics. The camera can compensate for these phenomena by using [Lens aberration correction].

  1. Select [Shooting: Lens aberration correction].

  2. Select an option.

  3. Select [Enable].

    • Confirm that the name of the attached lens and [Correction data available] are displayed (except when [Diffraction correction] is set).
    • If [Correction data not available] or a [Peripheral illumination] icon is displayed, see Digital Lens Optimizer.

Peripheral Illumination Correction

Vignetting (dark image corners) can be corrected.

Caution

  • Depending on shooting conditions, noise may appear on the image periphery.
  • The higher the ISO speed, the lower the amount of correction will be.

Note

  • The amount of correction applied will be lower than the maximum correction amount applied with Digital Photo Professional (EOS software).
  • Peripheral illumination is corrected automatically in Basic Zone modes when correction data is registered on the camera.

Distortion Correction

Distortion (image warping) can be corrected.

Caution

  • Specifying distortion correction may subtly change the angle of view, resulting in images that are cropped a little and seem slightly less sharp.
  • The amount of image cropped may vary between still photos and movies.

Note

  • With RF lenses, distortion correction during movie recording is supported.

Digital Lens Optimizer

Various aberrations from lens optical characteristics can be corrected, along with diffraction and loss of resolution.

If [Correction data not available] or [Peripheral illumination] is displayed by [Digital Lens Optimizer], you can use EOS Utility to add the lens correction data to the camera. For details, refer to the EOS Utility Instruction Manual.

Caution

  • Depending on shooting conditions, noise may be intensified together with the effects of correction. Image edges may also be emphasized. Adjust Picture Style sharpness or set [Digital Lens Optimizer] to [Disable] as needed before shooting.
  • The higher the ISO speed, the lower the amount of correction will be.
  • For movie recording, [Digital Lens Optimizer] will not appear. (Correction is not possible.)

Note

  • Enabling [Digital Lens Optimizer] will correct both chromatic aberration and diffraction when you shoot, although these options are not displayed.

Chromatic Aberration Correction

Chromatic aberration (color fringing around subjects) can be corrected.

Note

  • [Chromatic aberr corr] is not displayed when [Digital Lens Optimizer] is set to [Enable].

Diffraction Correction

Diffraction (loss of sharpness caused by the aperture) can be corrected.

Caution

  • Depending on shooting conditions, noise may be intensified together with the effects of correction.
  • The higher the ISO speed, the lower the amount of correction will be.
  • For movie recording, [Diffraction correction] will not appear. (Correction is not possible.)
  • The effect of diffraction correction cannot be checked on the screen at the time of shooting.

Note

  • [Diffraction correction] is not displayed when [Digital Lens Optimizer] is set to [Enable].
 

Caution

  • General precautions for lens aberration correction

  • Lens aberration correction cannot be applied to existing JPEG images.
  • When using a non-Canon lens, setting the corrections to [Disable] is recommended even if [Correction data available] is displayed.
  • Magnifying the periphery of the image may display parts of the image that will not be recorded.
  • The amount of correction (except diffraction correction) is less for lenses that do not provide distance information.

Note

  • General notes for lens aberration correction

  • Effects of lens aberration correction vary by lens and shooting conditions. Also, the effect may be difficult to discern depending on the lens used, shooting conditions, etc.
  • If the correction is difficult to discern, magnifying and checking the image after shooting is recommended.
  • Corrections are applied even when a life-size converter is attached.
  • 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).
  • If necessary, refer to the EOS Utility Instruction Manual as well.
