151 Lens Correction

Reduces distortions and lateral chromatic aberrations occurring due to lens properties.

Distortion

Distortion is a 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 small diameter lens, and straight walls or the horizon in an image appear curved.

Pincushion distortion

Barrel distortion

Lateral chromatic aberration

Lateral chromatic aberration is a phenomenon in which the magnification of an image varies according to the colors (wavelengths of light) when a picture was taken, and may cause a blurred image. Chromatic aberration occurs more easily at shorter focal lengths.
