How are zoom lenses made?
A simple scheme for a zoom lens divides the assembly into two parts: a focusing lens similar to a standard, fixed-focal-length photographic lens, preceded by an afocal zoom system, an arrangement of fixed and movable lens elements that does not focus the light, but alters the size of a beam of light travelling through
Do cameras use convex or concave lenses?
Convex lenses are used widely in the camera, not only focus on an image but also to magnify it. Almost all lenses of cameras consist of a convex lens followed by a concave lens, followed by a second convex lens.
