Sony E 20mm f/2.8 Lens

Compact wide-angle prime lens

Shooting stills or movies, this slim (20.4 mm), 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 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.
