Chromatic aberrations are caused by different wave lengths (in this case representative of colors) being manipulated slightly differently by your lens and thus arriving at the sensor in slightly different locations. As such, they are intrinsically attributes of your lens. You can minimize them by not adding unnecessary glass (cheap filters mostly) and by ...
