Is the sony e 18 55mm f 3 5 5 6 oss good for travel?
Yes, for many trips, though it's a modest choice. It's stabilised and light, which the travel guide asks for, and it covers wide scenes, food and street shots with one lens. Its weak spot is reach. On APS-C it frames roughly like 27-82mm on full frame, so distant subjects and tighter portraits will feel short.
If you want more range from one lens, the Sony E 18-135mm f/3.5-5.6 OSS is a good travel zoom for APS-C bodies. For the most reach, the Sony E 18-200mm f/3.5-6.3 OSS LE is a lighter, cheaper version of the 18-200mm travel zoom.
Pick the 18-55 if you want the smallest bag. Go up to the 18-135 if you'd rather not change lenses on a busy street.
