I just came back from a Canadian Rockies trip, Banff NP and Jasper. 95% of the time, I used a 24-70. For landscape scenes that included a great night sky, I used a 17-35 2.8.
Joehel2 - what camera and sensor size were you using? I’ll be going to the same places in August and use a Sony a6500 with an APS-C sensor. I have a 10 - 18/f4. And a 18 - 200/ f4.5 /6.3
