Chromatic aberration compensation function (CAC)
The chromatic aberration compensation function is a function to automatically compensate for registration error that is caused mainly due to slight
chromatic aberration, which is hard to completely compensate with the lens itself, using the camera recorder unit, and to minimize lateral chromatic
aberration of surrounding image.
When the lens compatible with the chromatic aberration compensation function is mounted, if the camera has the chromatic aberration compensation
data of the lens, then the chromatic aberration compensation function is activated automatically.
