Not counted as wide-angle on the Sony a6400: Voigtländer Nokton 21mm f/1.4 E (21mm, frames like 32mm), Sigma 24mm f/1.4 DG DN Art (24mm, frames like 36mm), Sony FE 24mm f/1.4 GM (24mm, frames like 36mm), Sony FE 24mm f/2.8 G (24mm, frames like 36mm), Viltrox AF 24mm f/1.8 (24mm, frames like 36mm), Samyang AF 24mm f/1.8 FE (24mm, frames like 36mm), 7Artisans AF 24mm f/1.8 (24mm, frames like 36mm), Sigma 24mm f/3.5 DG Contemporary (24mm, frames like 36mm), Tamron 24mm f/2.8 Di III OSD M1:2 (24mm, frames like 36mm), Meike AF 24mm f/1.4 MIX (24mm, frames like 36mm), TTArtisan AF 24mm f/3.8 mini (24mm, frames like 36mm), Zeiss Batis 25mm f/2 (25mm, frames like 38mm). They are wide lenses on full-frame, but the Sony a6400's 1.5× crop makes them frame tighter than 30mm-equivalent, so they are left out of this list. They are still in the full Sony a6400 table.
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. That works against you here: the widest option, the Laowa 9mm f/2.8 Zero-D, frames like 14mm — not as wide as its marked number suggests. For a genuinely wide view on the Sony a6400 you want a lens marked around 16mm or shorter.

Source page states "Length and weight are for Sony E-mount", so 570g is the Sony E figure (the nikon-z entry's 585g comes from a different source and is not in conflict).) |
