Zoom Lens

What is Zoom Lens?

A zoom lens is a type of camera lens that has a variable focal length, allowing the photographer to adjust the angle of view and magnification of the subject without physically moving the camera.

With a zoom lens, the focal length can be adjusted by rotating a zoom ring on the lens barrel, typically marked with focal length numbers. This allows the photographer to zoom in or out on the subject, creating a more dynamic composition. Zoom lenses are popular among photographers who need to be versatile and shoot a wide range of subjects, such as photojournalists or event photographers. They are also popular for travel photography, as they allow the photographer to capture a variety of scenes without carrying multiple lenses. However, it is important to note that zoom lenses can be more expensive and often have a variable maximum aperture, which may limit the ability to shoot in low light. Additionally, zoom lenses can be heavier and bulkier than prime lenses, which may make them less convenient to carry and use.
