Our take on the Sony E 20mm f2.8 Pancake Prime Lens

The Sony E 20mm f/2.8 is a wide-angle pancake prime for Sony APS-C mirrorless cameras. Its 30mm full-frame equivalent field of view and very short barrel make it a natural walkaround and street lens. The f/2.8 aperture is modest for low light, and the lens relies on software correction for distortion, but it is small, light and quick to focus. Rivals like the Sigma 19mm f/2.8 and Sony's own 16mm f/2.8 trade similar speed for different framing; reviewers tend to call the 20mm the sharper of Sony's pancakes.

Questions and answers

Is the 20mm f/2.8 good for street photography?
Yes. The 30mm-equivalent view and tiny barrel make it easy to carry and quick to frame with. The modest aperture is the main trade-off in dim light.
How does it compare with the Sony 16mm f/2.8 pancake?
The 20mm is narrower and generally sharper across the frame in reviews. The 16mm is wider but softer, especially at the edges.
Does it work on full-frame Sony bodies?
It is an APS-C E-mount lens. On a full-frame body it works in crop mode, giving a lower-resolution image.
Is the lens stabilized?
No. It has no optical stabilization, so rely on in-body stabilization if your camera has it.
What is in the box?
The lens comes with front and rear caps. A hood and pouch are not included.

At Amazon, for $378.00, as of our latest check.
