ZOOMLENS Meaning and
Definition
-
A zoom lens refers to a type of camera lens that possesses an adjustable focal length, enabling it to produce varying levels of magnification. Such a lens is designed to provide the photographer or user with the flexibility to shift from a wide-angle field of view to a narrow, telephoto magnification without requiring a lens change. This enables the photographer to zoom in or out, capturing subjects at different distances, by conveniently adjusting the lens rather than physically moving closer or further away.
A zoom lens typically comprises several lens elements that work together to achieve the desired focal length. When zooming in, the lens elements move to extend the focal length, bringing faraway objects closer, while zooming out involves the contraction of these elements, reducing the focal length and expanding the field of view.
Due to their versatility, zoom lenses are widely used in photography, particularly in situations where the subject is not easily accessible or requires rapid composition changes. They are commonly found in various types of cameras, such as digital SLRs, compact cameras, and video cameras. Different zoom lenses possess different focal length ranges, which can be identified by their magnification numbers.
Overall, the zoom lens has revolutionized photography by providing photographers with the convenience to effortlessly adjust focal lengths, thereby capturing subjects at desired distances and achieving versatile compositional choices.

Etymology of ZOOMLENS
The word "zoom lens" is a compound noun created by combining the noun "zoom" and the noun "lens".
The term "zoom" originates from the early 20th century and is derived from the verb "zoom", which means "to move quickly and smoothly closer to or away from something". This verb itself is believed to be onomatopoeic, imitating the sound produced by a moving object.
The word "lens" originates from the Latin word "lentis", meaning "lentil". It was originally used to refer to a piece of glass that had a convex shape similar to a lentil seed. The word "lens" subsequently evolved to specifically refer to the curved glass or other transparent material used to focus and channel light in optical devices such as cameras.
