Chromatic aberration is a lens defect that causes light of different colors to focus at different points, resulting in a loss of image sharpness and color accuracy. It is a common problem in photography, especially with wide-angle lenses.
There are a few different ways to avoid chromatic aberration. One way is to use a lens with a smaller aperture. This will reduce the amount of light that enters the lens, and it will also help to focus the light more accurately. Another way to avoid chromatic aberration is to use a lens with a shorter focal length. This will also help to reduce the amount of light that enters the lens, and it will also help to focus the light more accurately.
