Best travel lenses for the Sony a6400
36 travel lenses that fit the Sony a6400 (Sony E mount) — one-lens range and low weight. Sorted brightest-aperture first; every spec from the manufacturer's catalog.
Start with the Samyang AF 45mm f/1.8 FE. At f/1.8 it is the brightest of the 36 travel Sony E lenses that fit the Sony a6400 — the full comparison is below.
It is a full-frame lens. It fits and shoots at full resolution, and the glass often carries over if you move to a full-frame body later — but for the same framing it is larger, heavier and dearer than a lens built for this sensor. The brightest APS-C option here is Tamron 11-20mm f/2.8 Di III-A RXD at f/2.8.
One limit of this table: it lists only Sony E lenses that mount natively on the Sony a6400 — lenses fitted through an adapter are not included here. See which mounts adapt to which.
What these focal lengths actually give you on the Sony a6400
The Sony a6400 has an APS-C sensor, so it sees a 1.5× crop of what each lens projects. Every focal length below therefore frames 1.5× tighter than its marked number. A 50mm on the Sony a6400 frames like 75mm, not the "normal" view its marked number implies.
