Difference between wide-angle fixed-focus lens and standard fixed-focus lens

It is difficult to get the dramatic effect of the rendered picture like a wide-angle lens or a telephoto lens. However, the visual effect of the standard lens has a natural sense of closeness, and the distance between the standard lens and the subject is moderate, so it is widely used in ordinary landscapes, ordinary portraits, snapshots and other photography occasions.
