Why does the wide-angle lens of the Redmi Note 13 Pro 5G take purple pictures?

The ultra-wide lens on the Redmi Note 13 Pro has a wide viewing angle. In order to maintain the clarity and sharpness of the image at a wide viewing angle, more optical elements and complex lenses are needed in the design. Therefore, axial chromatic aberration is more likely to occur when shooting with an ultra-wide lens. It is recommended to avoid using an ultra-wide-angle lens to shoot in extremely high-contrast areas, which can reduce the appearance of chromatic aberration. If you need to shoot complex scenes against the light, it is recommended to switch to the main camera.
