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
small
diameter
lens,
and straight
walls
or the horizon
in
the image appear curved.

• 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 was taken, and may cause a
blurred
image.
Lateral
chromatic aberration occurs more
easily
at shorter
focal lengths.
