Zoom lenses are a type of camera lens that allows for a greater range of focal lengths than standard lenses. They are ideal for capturing shots from a distance, such as wildlife or sports photography. Zoom lenses are available in a variety of sizes, from wide angle to telephoto, and can be used with both digital and traditional film cameras. They are also available in different mounts, including Canon, Nikon, and Sony, so you can find the right lens for your camera. Zoom lenses are often more expensive than standard lenses, but they offer greater flexibility and can be used for a variety of photography applications.
