What does lens aberration correction mean?

Having a chromatic aberration correction function in-camera allows you to reduce the effects of axial aberration without having to use a narrower aperture, and also the colour fringing from lateral aberration without having to change your focal length.

How do you use the EOS lens registration tool?


  1. Using EOS Utility Ver.
  2. Connect your camera and computer.
  3. Set the camera’s power switch to , and set the mode dial to a Creative Zone mode (such as


  4. Start up EOS Utility Ver.
  5. Click [Register lens aberration correction data].
  6. The [Register lens aberration correction data] window appears.

What is lens peripheral illumination correction?

By Julie Adair King. The Canon Rebel T3 and T3i offer Peripheral Illumination Correction, which adjusts image brightness around the edges of the frame. Some lenses produce pictures that appear darker around the edges of the frame than in the center, even when the lighting is consistent throughout.

What is meant by chromatic aberration of a lens?

Chromatic aberration is a phenomenon in which light rays passing through a lens focus at different points, depending on their wavelength. This photo shows chromatic aberration in the leaves of the trees in the upper right corner of the image.

What does lens correction do?

Lens Corrections is a tool within Lightroom’s Develop Module (hence I often refer to it as a “sub-module”) that allows fixing such lens problems as distortion, chromatic aberration, vignetting and perspective correction “non-destructively”, without leaving Lightroom.

How do you fix lens aberration?

Change your color image to black and white. Use lenses made of low-dispersion glasses, especially those containing fluorite. They can significantly reduce chromatic aberration. To reduce LoCA, simply stop down your lens.

How do I turn off camera lens correction?

In fact, I believe it should be off by default, so you probably added it to the camera default one day. Or you apply it in a preset on import. Select an image, press the Reset button to reset it to its camera defaults, uncheck the lens correction option, and then save this as the new camera default.

What is the EOS lens registration tool?

It allows the lens correction data to be uploaded to the camera. And to be applied to RAW files by Canon’s photo editor, Digital Photo Professional.

How do you fix chromatic aberration?

How to Avoid Chromatic Aberration?

  1. Use High-Quality Lenses. The first way to minimize chromatic aberration is to buy high-quality lenses.
  2. Avoid High Contrast Scenes. First of all, you can avoid situations that result in a lot of color fringing.
  3. Increase the Aperture Value.
  4. Keep Your Subject Close to the Center.

What is distortion correction?

When distortion control is applied to an image either in-camera or through software it corrects barrel or pin cushion distortion that occurs in images due to the characteristics of specific lenses. The Distortion Control data in camera can be updated to include data for the latest lenses from the Download Centre .

Should I turn off chromatic aberration?

Since Chromatic Aberration does not affect the frame rate it is all down to personal preference. However we recommend to turn it off if you favour stronger image quality in your games as it can add a slight blurriness to the image.

What causes lens aberration?

Lens dispersion causes chromatic aberration. The refractive index of the lens elements changes depending on the wavelength of light. In other words, different colors of light pass through a lens at different speeds, similar to how a prism separates white light into a rainbow.

What does diffraction correction do on Canon 5D?

A diffraction correction feature, therefore, is especially helpful in such scenes that require narrow apertures. Canon’s diffraction correction feature used to be a part of Digital Lens Optimizer, but is now an independent function accessible through the lens aberration correction menu.

Is there lens aberration correction in the EOS 5D Mark IV?

Now, we shall do the same for the 4 other features of the EOS 5D Mark IV’s lens aberration correction function, which includes the new distortion correction feature, previously unavailable in-camera. (Reported by: Ryosuke Takahashi)

How does Canon’s lens aberration correction function work?

Canon’s in-camera distortion correction function corrects based on lens data, ensuring appropriate corrections for barrel distortions (common at wide angles) and pincushion distortions (common at telephoto angles). Take a look at the examples below, and notice how the horizontal lines in the subjects are straighter in the corrected images.

Do you enable lens aberration correction in Sooc JPEGs?

SOOC Jpegs should incorporate lens corrections automatically. Not absolutely sure, but I think the EOS Lens Registration Tool can transfer data to the camera on later models. It does interact with DPP4 to provide Lens Correction to RAW format images.
