Which focal segment of micro-camera is most commonly used for traveling?

It depends on where you travel. If it's a city street or something like that, the 28-35mm humanistic focal section is the most commonly used. If you are visiting large buildings, stadiums and the like, it is commonly used for ultra-wide angles of 24mm and below. If you are shooting natural scenery in the wild, in addition to the wide-angle focal length, telephoto focal length is also very commonly used, especially in places with very open terrain such as mountains, grasslands and deserts, where telephoto is used a lot. If you go to these places to shoot wild animals, you have to use telephoto. However, no matter where you go, as long as you are shooting people, you are the one who uses the focal segment most. Therefore, the tourist lens is usually a lens with a very large zoom range to meet the needs of various focal lengths.
