201 Lens Correction Reduces distortions and lateral chromatic aberrations occurring due to lens properties. Distortion Distortion is the phenomenon in which the center of the image appears inflated (barrel distortion) or the center of the image appears pinched (pincushion distortion). Distortion occurs more easily when using a zoom lens or a lens with a small aperture, and straight walls or the horizon in the image appears curved. Shooting Settings 6 Pincushion distortion Barrel distortion Lateral chromatic aberration Lateral chromatic aberration is the phenomenon in which the magnification of the image varies according to the colors (wavelengths of light) when a picture is taken, and may cause a blurred image. Chromatic aberration occurs more easily at shorter focal lengths.
