E 20 mm F2.8 Wide-Angle Prime (SEL20F28)

Shooting stills or movies, this slim (20.4 mm), lightweight pancake lens offers outstanding performance. Use it for interiors, nature, snapshots, and more.

Coupled with α E-mount cameras from Sony, APS-C E-mount lenses deliver big camera performance.

Circular aperture for smooth bokeh
Smooth defocusing

Instead of a standard polygon-shaped lens aperture, this lens features a 7-blade circular aperture for more natural, rounded defocusing, or bokeh.

Refined optical performance

To optimize performance, aspherical lens elements maintain high contrast (even with the aperture wide open) and minimize distortion and flatness of the image plane.

Fast, agile focusing

A rear focusing mechanism means the lens barrel doesn’t move, enabling a more compact design, faster autofocus response, and reduced minimum focusing distances.

We have revised this page to reflect the following correction: Sony E-mount cameras were incorrectly listed as having SteadyShot, so that information was removed.
