E 20 mm F2.8
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.
Instead of a standard polygon-shaped lens aperture, this lens features a 7-blade circular aperture for more natural, rounded defocusing or ‘bokeh’.
To optimize performance, aspherical lens elements maintain high contrast (even with the aperture wide open) and minimize distortion and flatness of the image plane.
An rear focusing mechanism means the lens barrel doesn’t move, enabling a more compact design, faster autofocus response, and reduced minimum focusing distances.
Impressive optical performance for Sony cameras, precision engineered for versatility and reliability in a wide range of applications.
 Aspherical lens
MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
 Contrast (%)  Distance from optical center of lens (mm)  Max. aperture  F8 aperture  Spatial frequency  10 line pairs / mm  30 line pairs / mm  Radial values  Tangential values
