Understanding Spherical Aberration

In pho­tog­ra­phy, Spher­i­cal Aber­ra­tion is a defect in cam­era lens­es that caus­es light from dif­fer­ent points on the object being pho­tographed to come to a focus at dif­fer­ent points. Spher­i­cal Aber­ra­tion caus­es soft­ness of the image and some F‑stop num­bers to be incor­rect. Spher­i­cal Aber­ra­tion can be cor­rect­ed with lens ele­ments made of high­er qual­i­ty glass. There are
