Correction of Lens Aberrations
3
Peripheral light fall-off is a phenomenon that makes the image corners
look darker due to the lens characteristics. Color fringing along subject
outlines is called chromatic aberration. Image distortion due to lens
characteristics is called distortion. And decreased image sharpness due
to the aperture is called diffraction phenomenon. These lens
aberrations can be corrected. By default, the [Peripheral illum corr],
[Chromatic aberr corr], and [Diffraction correction] are set to
[Enable], and [Distortion correction] is set to [Disable].
If the setting screen displays [Correction data not available] or the
[
] icon, it means that the correction data for the respective lens is not
registered in the camera. See "Lens Correction Data" on page 197.
