A zoom lens, also referred to as the parfocal lens, allows the camera to vary the range of the shot from a long shot to a close-up and vice-versa by altering the focal length. They are used with cameras (for still photography, video and motion picture cameras), binoculars telescopes and various other devices.
Some types of zoo lenses are:
Short Zoom lens – They are best suited for wide and super wide range and offer a maximum range of 50-60mm. Though these lenses are usually 35-70mm f/3.4-4.5 and 28-70mm f/3.5-4.5 lenses, some brands of cameras also have 18-55mm f/3.5-4.5 lens.
Super Zoom lens – These lenses are used for covering huge ranges and wide-angles. They usually cover 18-200mm.
In the recent years, zoom lenses have become an indispensable part of a camera, especially for professional photographers and people who are passionate about photography. Some benefits for zoom lenses are as follows:
Versatility – These lenses give the photographer the opportunity to adjust the focal length of the camera and make a distant object appear close. This is especially helpful for wildlife photography, shooting portraits and the like.

A fast lens is usually preferred by professionals, though slow zoom lenses have also become popular in the recent years.
