I’d like to draw upon the vast wisdom of the forum. Next summer, my wife and I are taking a raft trip down the Colorado River through the Grand Canyon. 12 days in a raft and a waterproof bag to protect my stuff. My options are the Fuji XH1 and the Sony A7Riii, both of which are water resistant. Since my lens choices for both are currently some normalish primes and a few short teles, I need to get some lenses. I’m thinking a wide zoom and something else. I have no real feel for this so I would appreciate some suggestions.
