Best standard prime lenses for the Sony a6400
59 standard prime lenses that fit the Sony a6400 (Sony E mount) — the natural field of view — first prime territory. Lenses we can link to a new listing on Amazon US come first, each group sorted brightest-aperture first; every spec from the manufacturer's catalog.
Start with the Laowa Argus 35mm f/0.95 FF. At f/0.95 it is the brightest of the 59 standard prime Sony E lenses that fit the Sony a6400 — the full comparison is below.
It is manual focus — no autofocus on the Sony a6400. If you want autofocus for standard prime, the brightest AF option here is Viltrox AF 27mm f/1.2 PRO at f/1.2. 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 Viltrox AF 27mm f/1.2 PRO at f/1.2.

Stabilisation uses a marker in the manufacturer model name; no marker is not a negative claim. Price filters use a current price when available.
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.
