What are the main differences between a lens with a focal length range of 18-55mm and a lens with a focal length range of 18-140mm?

The main difference between a lens with a focal length range of 18-55mm and a lens with a focal length range of 18-140mm is the zoom capability. The 18-140mm lens has a longer zoom range, allowing you to capture subjects that are farther away compared to the 18-55mm lens. This means the 18-140mm lens offers more versatility in terms of composition and framing.
