Is it DA2 1 or DA 1650 for Pentax lens tourism?

I think it is better and more convenient to use DA 1650. If it's a cultural snapshot or something, it's better to use 2 1, but if it's a landscape, as I said earlier, it won't take a week and a half. If you happen to photograph a cliff. . . . And the general scenery is still a lot of medium and long focus. I read an article before saying: "The scenery is generally telephoto. You see a buddy from the photography team coming up to Wide Angle, it must be that he didn't have a good drink with the team leader last night. . "
