FAQ

What's the difference between the Sony FE 20mm f/1.8 G and the Laowa 9mm f/2.8 Zero-D?
The Sony FE 20mm f/1.8 G is 20mm f/1.8 prime, full-frame; the Laowa 9mm f/2.8 Zero-D is 9mm f/2.8 prime, APS-C. Both fit the Sony E mount.

Which is better in low light, the Sony FE 20mm f/1.8 G or the Laowa 9mm f/2.8 Zero-D?
The Sony FE 20mm f/1.8 G — its f/1.8 maximum aperture lets in more light and gives more background blur than the f/2.8 of the other.

Do the Sony FE 20mm f/1.8 G and Laowa 9mm f/2.8 Zero-D fit the same camera?
Yes — both are Sony E mount lenses, so they fit Sony a7/a9/a1 (full-frame) and a6000-series (APS-C). Note the Laowa 9mm f/2.8 Zero-D is APS-C-only and won't fill a full-frame sensor.
