What lens was used to shoot Meili Snow Mountain?

Comrades who have been to Deqin many times give you a suggestion:

1. Shoot the snow-capped mountains with telephoto as the wide angle. 200mm telephoto has just begun, so it's just right for you to take Longteng150 ~ 600 mm.

2. Shooting scenery, wide angle is necessary, 17mm just started, Nikon users 14 24 is necessary.

Look, wide angle, telephoto. One camera and two mirrors are enough. You don't need two cameras, and you can take pictures of the scenery slowly without grabbing the camera.
