Correction of Lens Aberrations due
3
to Optical CharacteristicsN
Peripheral light fall-off is a phenomenon that makes the image corners
look darker due to the optical characteristics of the lens. Color fringing
along subject outlines is called chromatic aberration. Image distortion
due to optical characteristics of the lens is called distortion. And
decreased image sharpness due to the aperture is called diffraction
phenomenon. These lens aberrations can be corrected.
By default, [Peripheral illum corr], [Chromatic aberr corr], and
[Diffraction correction] are set to [Enable], and [Distortion
correction] is set to [Disable].
If the lens correction data is registered (saved) in the camera,
peripheral illumination corrrection, chromatic aberration corrrection, and
diffraction correction will be applied in Basic Zone modes. (In the <q>
mode, distortion correction is also applied.)
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 204.
