Twenty millimeters is the width we reach for first, and this is the lens that makes the case. Its 94-degree view takes in a small room or a whole treeline without the hard corner stretch that a 14mm puts on everything near the edges. That difference matters more than the numbers suggest: a 20mm frame still looks like a place, where a 14mm frame often looks like a lens.
The f/1.8 aperture is what separates it from the zooms here. Wide open it holds a handheld interior at a shutter speed you can live with, and it keeps stars as points rather than smears, which is why night skies and dim rooms are where this lens earns its keep. Two XD linear motors move focus quickly and, usefully for video, almost silently.
At 13.2 ounces it balances on a compact body instead of pulling it forward, and it is the lens we leave mounted when we do not know what we will be shooting. Focus is close enough to fill the frame with a coffee cup or a flower while the background stays straight, which turns a wide angle into something you can use for details too.
The limit is built into the focal length: in a tight bedroom or a small bathroom, 20mm has you backing into a wall. That is the one situation where the 16mm or the 14mm below earns its place. Everywhere else, from landscape to street to a walk after dark, this is the safest place in this group to put your money.
Pros
- 94-degree view with clean corners
- f/1.8 for night skies and dim rooms
- 13.2 ounces on a full-frame body
- Quiet dual XD linear motors
Cons
- Runs out of width in tight interiors
We recommend it to most full-frame Sony shooters: 94 degrees looks wide without looking warped, f/1.8 handles night scenes, and 13.2 ounces rides all day.
