Is the sony fe 70 200mm f 4 g oss good for travel?
Not really, as a one-lens travel choice. The Sony FE 70-200mm f/4 G OSS is a telephoto zoom, and it starts at 70mm, so it won't cover the wide scenes, street shots, or interiors that make up most of a trip. It's also a fair bit to carry. On the plus side, it's stabilised, which helps with handheld shots in dim churches and markets.
I'd use it as a second lens for wildlife, sport or distant details, and pick a wider zoom for everyday travel. My travel picks explain the options, and the travel checklist covers the points that matter most, especially size and weight. You can see the full lens details on the Sony FE 70-200mm f/4 G OSS page.
