lens aberrations

Lens aberrations are imperfections in a camera or optical system that cause image details to appear distorted or blurry. They occur because lenses can't perfectly bend light rays to a single point, leading to issues like blurring edges (spherical aberration), color fringing (chromatic aberration), or uneven focus across the image (astigmatism). These aberrations reduce the clarity and accuracy of the picture. Advanced lens design and correction techniques minimize these effects, resulting in sharper, more accurate images.
