Viewfinders are nice for when it is harder to view the screen, bright cross lighting, etc. Some viewfinders have a wider field of view than the camera lens, allowing you to anticipate what is coming into frame. Originally put on digital cameras because they were not immediately updating views on the screen at the time, and running the viewscreen runs down the battery faster .
