What is the main advantage of using a zoom lens?

The main advantage of using a zoom lens lies in its ability to provide a range of field of views. Unlike a prime lens, which has a fixed focal length and can only capture images from one specific perspective, a zoom lens allows the photographer to change the focal length and, consequently, the field of view without switching lenses. This versatility is particularly beneficial in dynamic environments where quick adjustments are necessary, such as when capturing subjects at various distances or when the composition needs to change rapidly.

This capability enables users to frame their shots more effectively and creatively, making zoom lenses a popular choice for various photography styles, including wildlife, sports, and event photography, where subjects may move closer or farther away. The flexibility to zoom in for detail or zoom out for context is a significant advantage that enhances the overall shooting experience and allows for greater creative expression.
