If you are going to take same landscape like mountain ranges it will be useful.
I only use 1 lens during my Mt Kinabalu trip. And that is a 17-40mm. It is more then sufficient for my needs.
Like I mention. Mountain scapes to me looks nicer on UWA shots then zoom shots.
Zoom too much, you will omit the clouds, and the surroundings of the ranges.
And your zoom shoots will not bring u much memories of the "perilous" journey you took to trek through the mountains.
Weight is also an issue when u trek on mountains and you may not have so much space to use your zoom lens to shoot and end up missing some shoots.
