Best wide angle lens for the sony a7?

For the Sony a7, I'd start with the Sony FE 16-35mm f/2.8 GM II. It covers a wide range, and the constant f/2.8 keeps exposure steady as you zoom, which helps when you're changing framings quickly.

If you'd rather have a prime, the Sony FE 14mm f/1.8 GM is my pick. It's properly wide, and the fast aperture helps in dim scenes. If you want even more light and don't mind a bigger lens, the Sigma 14mm f/1.4 DG Art is the one to look at.

The a7 has no stabilisation in the body, so keep your shutter speed up or choose stabilised lenses for slow shots. For more on what the f-number means, see Lenses.
