Compact wide-angle prime lens
E 20mm F2.8 Wide-Angle Prime (SEL20F28)
Shooting stills or movies, this slim (20.4mm), lightweight pancake lens offers outstanding performance. Use it for interiors, nature, snapshots and more.
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 optimise performance, aspherical lens elements maintain high contrast (even with the aperture wide open) and minimise 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.
Lens Configuration
Impressive optical performance for Sony cameras, precision engineered for versatility and reliability in a wide range of applications.
