Best travel lens for the sony zv e10?
For the ZV-E10, I'd start with the Sony Vario-Tessar T* E 16-70mm f/4 ZA OSS. It covers roughly 24-105mm in full-frame terms, which is about as close to one-lens travel coverage as you'll get. The body has no stabilisation of its own, so the OSS matters for dim churches and museums.
If you want something lighter, the Sony E PZ 16-50mm f/3.5-5.6 OSS is smaller and still stabilised, though it stops at a shorter telephoto.
For evenings and food, add a small fast prime such as the Viltrox AF 9mm f/2.8 Air or the 7Artisans 6mm f/2. The travel guide explains why size and weight should decide the kit.
