Buy a Sony RX10 IV with its range of 24mm-600mm (35mm equiv on a 1" sensor) and remarkable Zeiss lens if you want a travel camera with an extensive zoom range. You are not going to get that in a FE GM lens. I think the 70-200mm GM II is about the extent of what they will offer, with a 24-70mm GM II as its accompaniment. The latest version of the "holy trinity" could be: 12-24mm GM, 24-70mm II GM, 70-200mm II GM.
