Photography lovers are more suitable for taking pictures of their families and traveling. Is it necessary to buy a lens with a focal length of 70-200?

Medium telephoto is suitable for portrait shooting, and long zoom is very convenient to use. At the same time, telephoto can also shoot flowers and scenery that can't be in front, and can filter out some distractions that affect the main body, such as filtering out redundant branches when shooting close-ups of buildings. In short, telephoto is also widely used. If you have enough budget and can carry it, you should have one. Usually a wide-angle zoom, a medium-long zoom and a medium-range fixed focus are enough fun.
