How about Canon beginners?

Hello! Canon EF 70-200/4L USM (Xiao Xiaobai) Price: 5170 yuan Xiao Xiao Bai is the most commonly chosen mid-telephoto zoom lens by ordinary Canon SLR users, although it does not have a charming F2.8 aperture compared to Xiao Bai. But it has lost a lot of weight, which brings excellent portability. The weight is very suitable for street sweeping and traveling. Many professional photographers also choose smaller lenses when they need to move frequently for shooting. Canon EF 70-200/4L USM is a high-performance L series telephoto zoom lens. Since the maximum aperture of the design is f/4, it is smaller and lighter. Internal focusing system and ring ultrasonic motor make focusing fast and quiet. Because the front lens group does not rotate during focusing, the lens can be easily connected and used with a polarizing filter. The tripod mount can also be used on the EF300mm f/4L USM.
