Best travel lens for the sony a7c ii?
For travel on the a7C II, I'd start with the Sony FE 24-105mm f/4 G OSS. It's the one-zoom kit the travel guide describes: wide enough for streets and interiors, long enough for portraits and details. The OSS stabilisation helps when you're shooting handheld in a dim church.
If you want to pack lighter and don't need that much reach, the Sony FE 28-60mm f/4-5.6 is the other one I'd consider.
For evenings and food, add a small fast prime. The Sony FE 28mm f/2 is a sensible choice to carry alongside whichever zoom you pick. The travel guide has the rest of the packing list.
