I would strongly join those who have recommended taking a second body. I also support the idea of you taking your Batis 18 and Sony FE 70-300 lenses. But if I were going I would take your Sony/Zeiss 35 1.4 instead of the Sony/Zeiss 24-70. My experience, like many, many others, with the Sony/Zeiss 24-70 was soft corners. Very sharp in the center, so fine for people shots or as general purpose walk-about, but not acceptable IMHO for landscapes. Have a great trip!
