Spherical aberration occurs when light rays from a lens converge at different points, leading to unequal sharpness across an image, often resulting in blurred edges.
This optical problem is inherent in all spherical lenses, causing images to lack uniform sharpness and clarity, as the edges may appear visibly distorted.
Spherical aberration is tied to how light travels through lenses; thus, many photographers may not realize their images are affected until they notice blurring.
While spherical aberration can compromise image quality, it may not be a significant concern for photographers focusing on subjects with a soft bokeh background.
